Abstract
A novel braking retarder adopts a friction disc type braking structure and is arranged on a transmission shaft between a gear-box and a driving axle, wherein, each side of the two sides of a friction brake disc is provided with a group of brake chambers, brake calipers and friction plates; the brake chambers push a wedge and generate reinforcement, then transmit the force to the friction plates on the two sides of the friction brake disc through the brake calipers, thereby generating brake torque on the friction brake disc. The gap between each group of the friction plates and the two sides of the friction brake disc can be adjusted through gap adjusting rods of the friction plates.
Description
The present invention relates to a kind of automobile brake reducer, it is arranged on the transmission shaft between gearbox and the ransaxle, and transmission shaft is produced braking moment, stops it to rotate, and reaches the purpose slow to wheel braking.
The braking system of domestic and international most heavy vehicles mainly relies on the wheel hub braking at present, if long-time descending of vehicle or overload are travelled, frequent braking can be accelerated the wearing and tearing of brake block, and the braking force deficiency increases the brake lining heat fade.In order to increase the vehicle braked safety coefficient, the auxiliary braking system that is arranged between gearbox and the ransaxle is used at automotive field.Well-known category product together has: a kind of is the electric convolution brake reducer, has begun at home to use, and it is to rely on electric current to produce the opposing torque that rotates with transmission shaft, stops its rotation, produces the slow effect of braking.Another kind is the hydraulic braking retarder of Sweden Scania company, rely on hydraulic oil to pump between rotor and the stator, to the rotation generation damping function of rotor, the rotational speed of the rotor that slows down, thereby also slowed down the rotating speed of transmission shaft, played the effect of the slow braking of vehicle.
The shortcoming of these two kinds of brake reducers is:
First kind of electric convolution brake reducer, the coil that built-in copper cash twines, weight is big, and cost is higher.The coil that makes built-in aluminum steel winding into reduces weight and cost, can cause the slow scarce capacity of braking.
Second kind of hydraulic braking retarder belongs to Sweden Scania house journal product, and can the manufacturing technology complexity be used still unknown in China.
In order to satisfy the demand of domestic motor market, the invention provides a kind of novel brake reducer, it is to utilize ripe friction-disc braking principle, be arranged on the transmission shaft between gearbox and the ransaxle, apply braking moment to transmission shaft, affact on the wheel by ransaxle, thereby realization is to the slow braking of wheel.
The technical solution used in the present invention is that brake disc, friction plate, brake calipers and supporting frame group are integral, and supporting frame is fixed on the vehicle frame, and brake disc is connected with transmission shaft by the intermediate propeller shaft flange.In order to increase braking moment, one group of brake chamber, brake calipers, friction plate are respectively arranged in the friction brake disk both sides, brake chamber is exerted pressure to brake calipers by inclined wedge augmenting, power is passed to the friction plate on brake disc two sides respectively, stop brake disc to rotate, transmission shaft is produced braking moment, make the vehicle slows travelling speed.
Characteristics of the present invention are to utilize the friction-disc braking principle, technology maturation, and critical piece can directly utilize the general part of the existing vehicle in market; Structural behaviour is reliable, and manufacturing process is simple, and is easy to maintenance, and the domestic similar products of weight ratio are light.
The present invention is further described below in conjunction with accompanying drawing.
Each component names is in the drawings: (1) friction plate gap regulating lever, (2) brake disc, (3) friction plate, (4) brake calipers, (5) supporting frame, (6) intermediate propeller shaft flange, (7) brake chamber and wedge.
Its structure characteristic is: supporting frame (5) is installed on the vehicle frame of automobile, and other parts in the accompanying drawing all are installed on the supporting frame (5).Wherein respectively arrange one group of friction plate (3), brake calipers (4), brake chamber and wedge (7) in brake disc (2) both sides; Brake disc (2) is connected as a single entity with intermediate propeller shaft flange (6), and intermediate propeller shaft flange (6) is connected with truck drive shaft; Friction plate gap regulating lever (1) can be adjusted the return gap of brake disc (2) two sides friction plate (3).
Working procedure is: during automobile running, brake disc (2) rotates with transmission shaft; During braking, brake chamber and wedge (7) pass to brake calipers (4) to power, and brake calipers (4) is exerted pressure to brake disc (2) to two friction plates (3) two sides of this group, produce friction torque, stop the transmission shaft rotation that links to each other with brake disc (2).The size of control brake air chamber and wedge (7) application of force just can satisfy car brakeing or slow requirement.
Wearing and tearing along with friction plate (3), the return gap of it and brake disc (2) is strengthened, and braking distance is increased, and causes the too much loss of the compressed-air actuated air inflow of brake chamber, suitable spin friction sheet gap regulating lever (1) is adjusted the contact gap of friction plate (3) and brake disc (2).
Claims (2)
1. a novel brake reducer adopts the friction-disc brake structure, is arranged on the transmission shaft between gearbox and the ransaxle; It is characterized in that: respectively arrange one group of brake chamber, brake calipers, friction plate in the friction brake disk both sides.
2. promote inclined wedge augmenting according to the described brake chamber of claim 1,, produce braking moment at friction brake disk by the friction plate of brake calipers power transmission to the friction brake disk both sides.
