Description

Technical Field

[0001] This utility model belongs to the field of motor vehicles, and relates to brake separators, and more particularly to a separator assembly. Background Technology

[0002] Existing multi-disc wet brakes typically use internal hydraulic oil to directly push a piston axially, thereby pressing the dynamic and static friction pads to generate frictional resistance torque and brake the vehicle. For example, CN202022260800.0 discloses a wet brake suitable for large-tonnage axles, which includes a wet brake body with static and dynamic friction pads, a detachable cylindrical pin, a brake wheel, and a cylinder. However, for axle housings with specific spatial requirements, a separator is needed to convert external radial force into axial thrust, which is not adequately met by conventional direct axial braking separators. Utility Model Content

This device can be built into the axle housing and converts external radial force into axial thrust to meet braking requirements.

[0004] To achieve the above objectives, the present invention provides a separator assembly comprising multiple sets of spaced friction plates and steel plates. Two push plates are arranged at the axial symmetrical center of the friction plates and steel plates. Multiple return springs are evenly distributed around the axis of the friction plates and steel plates between the two push plates. The two ends of the return springs are connected to different push plates. A pair of spaced connecting members are provided at the distal ends of the two push plates. The connecting members are used to transmit the radial force of the hydraulic action to the push plates and the return springs.

[0005] Preferably, the initial state of the return spring is a pre-stretched return spring.

[0006] Preferably, the push plate end face is provided with a plurality of mounting grooves corresponding one-to-one with the reset springs, and the mounting grooves are provided with hook holes for connecting to the reset springs, and the end of the reset springs bypasses the mounting grooves and hooks onto the hook holes.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Examples, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention provides a separator assembly comprising multiple sets of spaced friction plates 1 and steel plates 2. Two push plates 3 are arranged at the axial symmetrical center of the friction plates 1 and steel plates 2. Multiple return springs 4 are arranged between the two push plates 3, evenly distributed around the axis of the friction plates 1 and steel plates 2. The two ends of the return springs 4 are connected to different push plates 3. A pair of spaced connecting members 5 are arranged at the distal ends of the two push plates 3. The connecting members 5 are used to transmit the radial force of hydraulic action to the push plates 3 and the return springs 4.

[0023] Specifically, friction plate 1 and steel plate 2 form a friction group, with adjacent friction groups arranged close together. The friction groups on both sides can act on the contact plane of the axle housing and the cover. Connector 5 is used to contact the loading end of the external hydraulic radial force, i.e., to contact the push rod. The push rod is a wedge-shaped surface. The push rod is hydraulically driven and can act on connector 5. Connector 5 acts on push plate 3, causing push plate 3 to deform. The balance between push plate 3 and return spring 4 is broken by the force transmitted from connector 5. The axial linear length of return spring 4 increases, thereby widening the distance between the two push plates 3. The friction groups on both sides of push plate 3 act on the corresponding axle housing and cover, thereby cutting off the power transmission between the half shaft and the axle housing and achieving braking. Overall, this device is an independent structure that can be built into the axle housing, making it easy to install and arrange. Its connecting part 5 accepts external hydraulic radial force, which can ultimately be converted into axial thrust, thereby driving the friction plate 1 and steel plate 2 to move axially until they are pressed against the axle housing plane to generate frictional resistance and achieve braking. The design is ingenious, safe and reliable, and can meet the space requirements for radially arranged hydraulic power.

[0024] To improve braking efficiency, the return spring 4 in the initial state of this invention is a pre-stretched return spring 4. In this way, when the hydraulic radial force acts on the connecting piece 5, the pre-stretched return spring 4 can undergo instantaneous deformation to ensure the immediacy of braking.

[0025] Furthermore, the push plate 3 provided by this utility model has multiple mounting grooves 6 corresponding one-to-one with the return springs 4 on its end face. Each mounting groove 6 has a hook hole 7 connected to the return spring 4, and the end of the return spring 4 bypasses the mounting groove 6 and hooks onto the hook hole 7. The mounting groove 6 facilitates the connection of the return spring 4 to the hook hole 7, and also alters the local force-bearing capacity of the push plate 3 surface, causing the push plate 3 to deform under the pushing force of the connecting member 5, resulting in an axial force component. This causes the return spring 4 to undergo axial elongation, thereby pushing aside the friction assemblies on both sides of the push plate 3 and acting on the bridge housing and cover to achieve braking.

[0026] like Figure 2 and Figure 4 As shown, the groove of the mounting groove 6 provided by this utility model faces the center of the push plate 3 and the diameter gradually decreases. The structural design features of the mounting groove 6 can make the push plate 3 deform as expected after being pushed, and in conjunction with the return spring 4, complete the braking process.

[0027] To improve the uniformity of force distribution on both sides of the push plate 3 during braking, this invention provides multiple spherical spiral inclined tracks 8 concentrically distributed with the distribution trajectory of the return spring 4 on the opposite surfaces of the two push plates 3. Steel balls 9 are arranged within the spherical spiral inclined tracks 8. The spherical spiral inclined tracks 8 between the two push plates 3 are symmetrically distributed on both sides of the steel balls 9. The spherical surface of the steel balls 9 contacts the spherical surface portion of the spherical spiral inclined tracks 8, causing the radial thrust transmitted from the push rod to generate an axial component force under the combined action of the steel balls 9 and the tension of the return spring 4. This ensures uniform and stable axial movement of the two push plates 3, providing stable pressure for the friction plate 1 and the steel plate 2 to combine, thereby generating a uniform and reliable friction braking force.

[0028] Furthermore, this utility model provides several φ20~26 steel balls 9 placed between two push plates 3. A spherical spiral inclined track 8 is designed between the contact surfaces of the push plates 3 and the steel balls 9, with an inclined angle of 25°~35°. The spherical spiral inclined track 8 is distributed around the concentric circles of the push plates 3. The spherical spiral inclined track 8 of the two push plates 3 are symmetrically located on both sides of the steel balls 9. This allows the steel balls 9 to generate corresponding inclined displacement and always interact with the push plates 3 during the process of the two push plates 3 being pushed by the connecting piece 5. The diameter of the steel balls 9 can prevent them from falling off the spherical spiral inclined track 8. In addition, multiple steel balls 9 provide sufficient bearing nodes, which is conducive to improving the dynamic balance performance of the push plates 3 and the return spring 4, thereby obtaining a stable and reliable braking action.

[0029] like Figure 2 and Figure 4 As shown, the push plate 3 has a radial opening 10 near the mounting connector 5. By adopting the design of the radial opening 10, the push force of the connector 5 on the push plate 3 can generate pressure in the circumferential direction, causing the push plate 3 to deform and then cooperate with the return spring 4 to enter the braking procedure.

[0030] To improve the practicality and utilization of the connector 5, the connector 5 provided by this utility model is a pin, with both ends of the pin movably inserted into the insertion holes 11 opened on the push plate 3. This invention designs the pin to be installed on the outer ring position of the push plate 3. After the two push plates 3 are symmetrically assembled with spherical spiral inclined tracks 8 on both sides of the steel ball 9, the two pins are also symmetrically distributed along both sides of the center line. This improves the uniformity of hydraulic force transmission in the braking direction, and the pins remain in the insertion holes 11 throughout the change in the distance between the push plates 3, thereby ensuring the repeatability and flexibility of the axial movement of the push plate 3.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
