Related to technology to prevent radiation from being emitted into the air.

Conventional vehicle brakes use as a friction material made of asbestos, which is a base material, solidified with resin. From a sanitary standpoint, it is required to switch to another material, but changing the material requires a multi-disc clutch type brake from the standpoint of durability.

特開昭55−107132号公報）。 On the other hand, it is known to use a multi-disc clutch for stopping or steering a vehicle. In addition, these multi-plate clutches use two types of friction plates, one on the driving side and one on the braking side, but these are usually connected to the shaft or case side via a spline (for example,

By the way, if this multi-disc clutch is to be housed inside the hub of a wheel, the spline connection between the multi-disc clutch and the hub, or between the clutch and the brake support plate, must be made inside the hub, and the joint location cannot be seen visually. Second, since it is integrated with the hub and wheel, which are connecting parts, it is extremely heavy, which significantly reduces workability and increases production costs.

The purpose of this invention is to solve the above-mentioned problems and provide a multi-disc clutch type brake with excellent assembly ease. It consists of a multi-plate clutch 15 provided in a brake chamber 15, which is connected to the brake support plate 1.
A pressure plate 19 and a friction plate 21 are interposed between the pressure receiving plate 18 supported on the inner surface of the pressure plate 18 and the hydraulic actuating means 25.
The pressure plate 19 is connected to the pressure receiving plate 18.
The friction plate 21 is supported slidably only in the axial direction, and the friction plate 21 is spline engaged with the shaft member 22 on the inner periphery, and the shaft member 22 is screwed to the hub 7 with a bolt 23 so that it can be attached and detached from the outer surface. Another feature is that a seal ring 13 is interposed between the hub 7 and the brake support plate 11.

Since the multi-plate clutch 15 is mainly attached to the brake support plate 11 except that the shaft member 22 is connected to the hub 7 by a bolt 23, by removing the bolt 23, the brake can be applied in the same manner as in the conventional method. The support plate 11 can be separated from the hub 7 or the brake support plate 11 can be assembled to the hub 7.

る。 Further, since the shaft member 22 spline-engaged with the friction plate 21 can be separated from the hub 7 by removing the bolt 23, it should be assembled to the multi-plate clutch 15 in advance before assembling the hub 7 and the brake support plate 11. By this, the hub 7 and the brake support plate 1
1, the complicated work of engaging the splines between the shaft member 22 and the friction plate 21 can be avoided.

いる。 The brake of this wheel 3 is constructed as follows. That is, the hub 7 provided on the shaft of the wheel 3
has an annular side opening, and the opening is covered with a brake support plate 11 to form an annular brake chamber 14 inside. Hub 7 and brake support plate 1
1 is machined after being cast from a light alloy, and a seal ring 1 is attached to the outer periphery of the brake support plate 11.
3 is fixed to maintain an oil-tight relationship with the hub 7, and a small amount of lubricating oil is contained inside.

る。 To explain the multi-plate clutch 15, a support bolt 16 made of a stud bolt is installed on the inner surface of the brake support plate 11, and a pressure plate 17 and a pressure receiving plate 18 are supported by the support bolt 16. Between the pressing plate 17 and the pressure receiving plate 18 are several clamping plates 19 that are slidably locked to the support bolt 16 only in the axial direction;
Friction plates 21 having spline teeth carved on the inner periphery are alternately arranged. A shaft member 22 engages with the friction plate 21 through spline teeth on its outer periphery, and is fixed to the inner surface of the hub 7 with bolts 23 . 25
is a hydraulic actuation means, three of which are equally spaced on the brake support plate 11, and consists of a cylinder 26 and a piston 27 fitted into the cylinder 26. One end of the piston 27 faces the hydraulic chamber, and the other end faces the hydraulic chamber. It faces the plate 17. Reference numeral 29 denotes an oil passage for connecting the inside of the hydraulic chamber 28 to a master cylinder operated by a brake operator (not shown), such as a brake lever.

る。 Next, the operation of this embodiment will be explained. When the brake is operated while the vehicle is running and the inside of the hydraulic chamber 28 is pressurized, the piston 27 moves to the left in the figure and moves the press plate 17 in the same direction. At this time, since the position of the pressure receiving plate 18 is fixed, each pressure plate 19
The gap between them disappears, and the rotation of the friction plate 21 is restrained by the pressure plate 19. The vehicle is thus braked. When the braking operation is released, the piston 27 retreats to the right, creating a gap between the pressing plate 17 and the pressure receiving plate 19, allowing the friction plate 21 to rotate and allowing the vehicle to run without being subjected to any braking. Become.

By removing the bolts 23, the brake support plate 11 can be separated from the hub 7 using conventional means.

避できる。 To assemble the wheel 2, the multi-plate clutch 15, including the shaft member 22, is assembled to the brake support plate 11 in advance, and the brake support plate 11 is aligned with the hub 7, and the axle 2 is inserted therethrough. Since the hub 7 and the brake support plate 11 are both positioned concentrically by the axle 2, next, slowly rotate the brake support plate 11 while looking inside through the bolt hole provided in the hub 7 to align the phases. . The bolt 23 is inserted at a position where the screw hole provided in the shaft member 22 is visible, and the shaft member 22 is fixed to the brake support plate 11. In this way, the troublesome spline connection between the friction plate 21 and the shaft member 22 can be performed relatively easily. That is, this avoids the problem of having to perform the complicated work of engaging the splines between the shaft member 22 and the friction plate 21 inside the brake chamber 14, which cannot be seen from the outside, when connecting the hub 7 and the brake support plate 11. can.

As described above, the present invention includes the hub 7 and the shaft member 22.
and the hydraulic actuation means 2.
5 is supported on the brake support plate 11, and the hub 7 is further supported on the brake support plate 11.
Since the seal ring 13 is interposed between the brake support plate 11 and the brake support plate 11, the inside of the brake chamber 14 is sealed at the same time as the brake support plate 11 is inserted into the side opening of the hub 7, so it is different from a conventional drum brake. Since it can be disassembled and assembled in almost the same way, the only additional work required is the step of removing the bolts 23, resulting in excellent workability and easy maintenance. In addition, when assembling a multi-plate clutch, the work is difficult, that is, the friction plate 2
1 and the shaft member 22 are assembled by the heavy wheel 3.
Since it can be carried out independently of the above, it has the effect of significantly reducing the burden on the worker.
