Embodiment 1

[0025] Embodiment one: see figure 1 As shown, a full disc brake includes a wheel 1, a housing 3, a friction plate assembly and a piston assembly, the friction plate assembly is composed of 4 rotating friction plates 5 and 5 sliding friction plates 4, and the rotating friction plates 5 and The sliding friction plates 4 are arranged at intervals, the rotating friction plates 5 are connected to the wheel 1 through the spline groove 10, the sliding friction plates 4 are installed on the housing 3 through the annular key groove 11, and the friction plate assemblies have The degree of freedom of axial movement, the piston assembly is located in the housing 3, respectively composed of the parking brake piston 2 on the left side of the friction plate assembly and the service brake piston 6 on the right side, and one end of the pistons on both sides is pressed against the On the friction plate assembly, a measuring rod 7 is inserted in the housing 3 corresponding to the return rod 8 of...

Embodiment 2

[0028] Embodiment 2: This embodiment is similar to Embodiment 1, except that the piston assembly includes a service brake piston 6 located on the right side of the friction plate assembly, and the left side of the friction plate assembly is against the housing 3 . The inner end of the measuring rod 7 is connected with the return rod 8 on the service brake piston 6 and moves axially together with the return rod 8 . The outer end of the measuring rod 7 is provided with a fixed value mark, and the friction plate assembly needs to be replaced when the measurement reaches the mark.

[0029] see figure 2 As shown: the wheel 1 rotates around the central axis, the wheel 1 is equipped with a rotating friction plate 5, the rotating friction plate can slide axially on the wheel 1, and the rotating friction plate 5 rotates with the wheel at the same time. The housing 3 is fixed on the bridge, and the sliding friction plate 4 is installed on the housing 3 and can slide axially on the hou...

Embodiment 3

[0031] Embodiment 3: This embodiment is similar to Embodiment 1, the difference is that the piston assembly includes two groups of service brake piston 6 and parking brake piston 2, both of which are arranged on the right side of the friction plate assembly, and the friction plate assembly The left side is against the casing 3 . The inner end of the measuring rod 7 is connected to the service brake piston 6 , and a sealing structure is provided between the service brake piston 6 and the housing 3 to seal the inner cavity of the housing 3 . At the same time, an annular groove can also be provided on the measuring rod, and a sealing ring can be arranged in the annular groove to form a seal with the housing insertion hole.

[0032] see image 3 As shown, the wheel 1 rotates around the central axis, and the wheel 1 is equipped with a rotating friction plate 5, which can slide axially on the wheel 1, and the rotating friction plate 5 rotates with the wheel 1 at the same time. Hou...

Abstract

The invention discloses a complete-disc brake comprising wheels, a shell, friction plate components and piston components. Rotating friction plates and sliding friction plates are arranged at intervals; the sliding friction plates are connected with the wheels; the sliding friction plates are arranged on the shell; all the friction plate components can freely move axially; the piston components are arranged in the shell; and one end of each piston component is supported against the friction plate components. The complete-disc brake is characterized by also comprising a measuring bar which is inserted in the shell, wherein the inner end of the measuring bar is supported against or fixed on the piston component or the friction plate components and the outer end extends out of the shell, andthe measuring bar is in axial sliding connection with an insertion hole which is disposed on the shell. Because the measuring bar is arranged in the shell, the friction of the friction plates can be observed directly outside the shell and detected conveniently without opening the shell and can be replaced in time, and further the driving safety is improved.

Description

technical field [0001] The invention relates to a vehicle brake, in particular to an all-disc brake. Background technique [0002] The brake is an important part of the car, and its function is to stop the moving vehicle. After years of development, brakes have gradually formed two technical forms, disc brakes and drum brakes. The drum brake is composed of a brake drum and a brake shoe. The brake drum is connected to the wheel for rotational movement. The brake shoe is connected to the bridge. The contact between the moving shoe and the brake drum generates frictional force to brake the vehicle, and when the brake shoe is contracted, the brake shoe is separated and the brake is released. There are two main types of disc brakes, one is caliper disc brakes and the other is full disc brakes. Among them, the caliper disc brake is composed of two parts: the brake disc and the brake caliper. The brake disc and the wheel are connected for rotational movement. The brake caliper a...
