Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an improvement of a brake device provided in an automobile or the like.

Prior Art A brake device including a wheel brake body and a ground brake body was proposed by the inventor and is already well known (for example, Japanese Utility Model Publication No. 16408/1983).

Problems to be solved by the invention Although the above conventional technology has improved braking effect compared to previous brake devices, the ground-contact brake body has a ground-contact piece that presses against the frozen road surface, snow surface, etc. Therefore, on well-maintained, flat, icy or snowy roads with few uneven surfaces or depressions, the vehicle may skid with the ground contact piece of the ground brake body in pressure contact, causing the steering wheel to be taken off. It is dangerous and improvements are desired.

The present invention is proposed in response to such a demand, and includes a ground brake body configured in a sled shape, and an angle of the ground brake body that can be changed in a V-shaped plane with respect to the direction of travel during braking. configure,
The object of the present invention is to provide a brake device suitable for use in winter, which exhibits a further improved braking effect and can safely stop the vehicle after an angle change on the above-mentioned flat frozen road surface, snowy surface, etc. with less risk of skidding. .

Means for Solving the Problems In order to achieve the above object, the present invention provides a grounding brake body which is constructed by attaching a grounding piece that is long in the front and back direction and has a substantially U-shaped side surface to a mounting piece, and is operated by manual handle operation. The present invention proposes a means of causing the ground contact brake body to touch the ground at the same time as changing the angle of the ground contact brake body in a V-shaped plane with respect to the traveling direction by depressing the brake pedal.

Function: Since the present invention consists of the above-mentioned means, if the ground brake body is brought into contact with the ground by manual handle operation and brake pedal depression operation, and the angle is changed in a V-shape in plane with respect to the direction of travel, it is possible to The contact area of the ground brake body with respect to the road surface, such as the road surface or the snow surface, becomes wider and running resistance increases, and at the same time, one edge of the ground contact brake body bites into the road surface, such as the frozen road surface or snow surface, and the brake is applied.

Embodiment To explain the drawings, in an automobile in which front and rear wheels 2, 2 are supported by axles 1, 1 on both front and rear sides of the automobile body, a pair of support rods 4, 4 are attached to an axle tube 3 of a rear axle 1. The mounting parts 4', 4' are mounted side by side, and the support rods are arranged parallel to each other in the front-rear direction, and a pair of vertical shafts 5, 5, which are passed through the axle 1 and the axle cylinder 3 in parallel, are used as axes. Configure it so that it can rotate. One end of a connecting rod 6, 6, 6, 6 is pivotally attached to both the front and rear ends of the supporting rods 4, 4, and a grounding brake body 7, 7 is pivotally attached to the other end of the connecting rod. It is configured to rise and fall by means of the connecting rods 6, 6, 6, 6, and to come into contact with and leave the frozen road surface or snow surface. The grounding brake bodies 7, 7 have grounding pieces 7', 7' formed long in the front-rear direction, side surfaces approximately U-shaped and attached to mounting pieces 7'', 7'', and lateral surfaces approximately curved. The other ends of the connecting rods 6, 6, 6, 6 are pivoted to these mounting pieces and connected to the supporting rods 4, 4. A fluid tank 8 for oil, compressed air, etc. is connected to the opposing inner surfaces of the rear parts of the ground-contact brake bodies 7, 7, and the tank is also connected to a brake pedal 9, so that when the pedal is depressed, , the ground brake bodies 7, 7 are rotated about the vertical axes 5, 5 by fluid pressure.
The rear side is pushed open in the direction of wheels 2 and 2, and the front side narrows, changing the angle from parallel to the direction of travel of the car to a V-shaped plane, and making contact with the road surface such as frozen road or snow. The ground contact area of the ground contact pieces 7', 7' is widened and the running resistance is increased, and the edge on one side of the ground contact pieces 7', 7' (the edge on the wheel side in Fig. 1) bites into the road surface. (See Figure 1). Also, among the connecting rods 6, 6, 6, 6, the one located on the front side is connected to the manual handle 10 with a wire etc., and when this handle is raised, the ground brake bodies 7, 7 are in the raised position. When it is tilted forward, the ground brake bodies 7, 7 are configured to descend and touch the ground (see Fig. 2).

Effects of the invention Since the present invention is configured as described above, when braking, the ground brake body is brought into contact with the road surface, such as a well-maintained flat frozen road surface or snow surface, and then or change the angle in a
Alternatively, if the vehicle is brought into contact with the road surface after changing its angle in a V-shape with respect to the direction of travel, one edge of the ground brake body will engage the road surface and the vehicle will be decelerated safely and quickly to a stop. This braking action is
When trying to brake while skiing, if you change the angle of the ski in a V-shaped plane with respect to the direction of skiing, the edge of one side of the ski will bite into the snow surface, causing the ski to decelerate and come to a stop. Demonstrated by principles.

Therefore, if the angle of the ground brake body is changed during braking, the risk of skidding and the risk of the steering wheel being taken away will be reduced, making it possible to stop safely and quickly, thereby achieving the intended purpose. can be achieved.
