Description

Car engine right mount

technical field

The invention belongs to car parts, in particular to a car engine right mount for installing a car engine.

Background technique

Many existing cars of the same brand but of different models all adopt the same body structure and match with different types of engines, that is, the size of the body structure remains unchanged, but the size and even the shape and structure of the engine have changed to a certain extent. As a result, the assembly relationship between the engine and the body changes. For example, the Lifan LF7130 model is based on the LF7160 by replacing the engine. The engine size of the original LF7160 is relatively large, and the distance between the engine and the right longitudinal beam of the car body is relatively short. It is only necessary to fix a bottom plate on the right longitudinal beam with screws, and then install a buffer block on the bottom plate. The top of the buffer block is fixed The limit screw, the shaft of the limit screw faces upward and is equipped with a limit nut. The limit screw is equipped with a load-bearing arm and an auxiliary suspension to connect with the engine casing to fix the engine; but the engine size of the LF7130 model is small , the distance between the engine and the right longitudinal beam of the car body is relatively long, the load-bearing arm is lengthened and thickened, and the auxiliary suspension is canceled at the same time, so the requirements for the strength, rigidity and stability of the engine right suspension are higher.

The disadvantages of the prior art are: the existing bottom plate, buffer block and limit screw mounting structure have low strength, rigidity and stability, poor load-bearing capacity, and cannot support the engine at a long distance.

Contents of the invention

The object of the present invention is to provide a car engine right mount with strong load-bearing capacity, which has high strength, rigidity and stability, and can support the engine at a long distance.

In order to achieve the above object, a right suspension device for a car engine according to the present invention includes a welding plate, a buffer block installed on the welding plate, and a limit screw fixed at the top of the buffer block. Above the buffer block, and set the limit nut, the key lies in: it also includes a U-shaped vertical plate, the U-shaped vertical plate includes the side vertical plate on both sides and the main vertical plate in the middle, and the concave space surrounded by the three vertical plates The welding flat plate is welded in the groove, the sides of the two side vertical plates are symmetrically bent outward to form a reinforcing plate, and the bottom edges of the two side vertical plates are symmetrically bent outward at 90° to form a bottom plate, which is connected with the reinforcing plate. The bottom edge of the board is fixedly connected, and the bottom board is provided with screw mounting holes.

The U-shaped vertical plate is added and fixed on the right longitudinal beam of the car body, which improves the strength, rigidity and low stability of the suspension bracket. The U-shaped vertical plate is formed by stamping, which has the advantages of convenient processing and low cost.

The sides of the two side vertical plates are symmetrically bent outward by 90° to form a reinforcing plate, and the lower end of the reinforcing plate is bent by 90° and attached to the bottom plate.

A steel plate is arranged on one of the bottom plates, the steel plate is parallel to the reinforcement plate, one side of the steel plate is welded on a side vertical plate of the U-shaped vertical plate, the lower end of the steel plate is bent by 90° and attached to the bottom plate .

Both the reinforcement plate and the steel plate can improve the bearing capacity of the U-shaped vertical plate and meet the strength, rigidity and stability requirements required for engine installation.

The bottom plate is provided with three screw installation holes, and the screw installation holes pass through the lower bent part of the reinforcing plate and the lower bent part of the steel plate respectively.

Three screws respectively fix the reinforcing plate and the U-shaped vertical plate, and the bottom edge of the steel plate and the U-shaped vertical plate on the right longitudinal beam of the car body to increase stability.

A "U"-shaped buffer frame is fixedly installed on the upper part of the buffer block, and rubber blocks are respectively installed on the outer sides of the "U"-shaped buffer frame, and the rubber blocks are respectively abutted against the two sides of the U-shaped vertical plate Riser.

The upper part of a side vertical plate of the U-shaped vertical plate is bent outward at 14° to 24°, and a vertical edge of the “U”-shaped buffer frame corresponding to the side vertical plate is bent outward at 14° to 24° bent, and the rubber block is sandwiched between the two.

The buffer block can absorb the shock of the longitudinal force, and the rubber block can absorb the shock of the lateral force.

The remarkable effect of the present invention is to enhance the load-bearing capacity of the right mounting device of the car engine, make it have high strength, rigidity and stability, and can support the engine at a long distance, and at the same time, it can also resist longitudinal force and lateral force The force acts as a shock absorber.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1, 2, 3, 4, and 5: a right suspension device for a car engine is composed of a welding plate 1, a buffer block 2, a limit screw 3, a limit nut 4 and a U-shaped vertical plate 5. A buffer block 2 is installed on the welded plate 1, and the top of the buffer block 2 is fixed with a limit screw 3. The shaft of the limit screw 3 is located above the buffer block 2, and the limit nut 4 is sleeved, and the U-shaped vertical plate 5 Including the side vertical boards on both sides and the main vertical board in the middle, the welded flat plate 1 is welded in the groove surrounded by the three vertical boards, and the sides of the two side vertical boards are symmetrically bent outward to form a reinforcement board 5b , the bottom edges of the two side vertical plates are bent outward symmetrically by 90° to form a bottom plate 5a, the bottom plate 5a is fixedly connected with the bottom edge of the reinforcing plate 5b, and the bottom plate 5a is provided with screw mounting holes 8.
