Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an equalizer device for a parking brake for an automobile, which transmits the operating force of an operating lever almost equally to a pair of left and right wheel brakes.

(Prior Art) In an automobile, in order to prevent the vehicle body from shifting when parking, a control knob provided near the driver's seat is operated to normally put the left and right rear wheel brakes into a braking state. In this case, in order to equalize the braking force of the left and right rear wheel brakes, an equalizer is provided between the operating lever and each rear wheel brake.

In general automobiles, the control lever is placed near the longitudinal center line of the car body, and the equalizer is also placed near the center edge of the car body, behind the control lever.
The equalizer is configured such that the input direction of the operating force is approximately along the center line of the vehicle body.

However, due to the structure of the car or for other reasons, if the control lever is located far away from the center line of the car body and placed on the side of the car body, the wires that transmit the operating force may become difficult to route, resulting in premature wear of the wires. ().

There was a problem with cars where resistance increased and operation became less precise.

(Object of the Invention) The present invention was made in view of the above circumstances, and is applied to an automobile parking brake that transmits the operating force of an operating lever provided on the side of the vehicle body to a pair of left and right wheel brakes via an equalizer. An object of the present invention is to provide an equalizer device for a parking brake for an automobile in which wiring of a wire for transmitting operating force is not strained, and wear and resistance of the wire are reduced.

(Structure of the Invention) In order to achieve this object, the present invention includes a support plate rotatably supported on the vehicle body near the center of the vehicle body m7;
A pair of pulleys of approximately the same diameter are pivotally supported on this support plate at positions approximately symmetrical to the support axis of the support plate, and the pulleys are wound diagonally around both pulleys, and both ends are connected to each of the wheel brakes. and an input end wire, one end of which is connected to the operating lever and the other end of which is connected to the support plate, and each of the wires is routed substantially transversely to the vehicle body at least near the support plate. However, there is )-c. The present invention will now be described in detail based on the illustrated embodiments.

(Example) Fig. 1 is a plan view of a one-seater four-wheeled vehicle to which an embodiment of the present invention is applied, Fig. 2 is a plan view of an equalizer, and Fig. 3.4
The figures are a view from the ■ arrow and a view from the ■ arrow.

In FIG. 1, reference numeral 10 denotes a vehicle body, and 12.12 denotes steering front wheels provided symmetrically with respect to the longitudinal center line A of the vehicle body 10.
14.14 is the driving rear wheel as well. Each rear wheel 14 is equipped with a mechanical brake 16.16.

18 is a driver's seat provided near the center of the vehicle body, and 20 is a steering handle provided on the center line. Driving seat 1
An operating lever 22 is disposed on the right side of the vehicle 8, that is, on the right side of the vehicle body.

Reference numeral 24 denotes an equalizer, which is provided near the center line A below the driver's seat 18. The equalizer 24 includes a support plate 28 rotatably supported on the vehicle body by a support shaft 26, and pulleys 30 (30a, 30a, 30b) and one pulley 3
0, an output side wire 32 diagonally wound around the pulley 30a, a U-shaped bracket 36 pivotally supported on the support shaft 34 of one of the pulleys 30a, and an input side wire 38 secured to this bracket 36. It is equipped with The output wire 32 extends from the pulley 30 to the vehicle body (almost sideways, in a direction T, that is, approximately perpendicular to the center line A).
is connected to. Note that at this time, the support plate 28 is located substantially long in the front-rear direction.

Similarly, the input end wire 38 extends laterally with respect to the vehicle body and is connected to the operating lever 22.

Therefore, due to the operating force of the operating lever 22, the input wire 38
When is pulled, the support plate 28 rotates around the support shaft 26, the output wire 32 is simultaneously pulled toward the equalizer 24, and the rear wheel brakes 16 and 16 are simultaneously activated. The output side wire 32 is a pulley 30a.

Since it is wrapped around 30b, at this time the pulley 30a,
30b rotates slightly. Both pulleys 30a, 30b
are symmetrical about the support shaft 26 of the support plate 28, so the operating force of the brake 16 by the wire 32 is equal on the left and right sides. Also wire 3
2 is located almost sideways to the vehicle near the equalizer 24, so the wiring between the wire 32 and each brake 16.16 can be curved greatly to make it almost symmetrical, and the distribution of the braking force of the brakes 16.16 can be made even more equal. On the other hand, the input wire 38 can be connected to the operating V-bar 22 and the equalizer 24 just by bending it once. Therefore, the wires 32 and 38 are not strained, and the pulley 30 also rotates, so the wires 32 and 38 are not strained.
34 wear and resistance is reduced.

Operation becomes easier. Further, the structure is simple because only the support plate 28 with the pulley 30 is supported on the vehicle body.

In this embodiment, the input end wire 38 is connected to the support shaft 34 of the pulley 30a via the bracket 36, but the input side wire 38 is directly connected to the support plate 28 so as to apply a rotational force to the support plate 28. Of course, you can.

(Effects of the Invention) As described above, the present invention pivots the support plates of the two pulleys near the center line of the vehicle body at approximately the center of both pulleys, and winds the output side wire diagonally around both pulleys. This is because the input and output wires were routed sideways to the vehicle body.

Wire routing is not strained, reducing wire wear and resistance. Therefore, the durability of the wire can be increased. Not only does it reduce the resistance of the wire.

The pulley also rotates down, making operation smooth and light.
