Description

Technical Field

[0001] This utility model relates to the field of tractor braking technology, and in particular to a braking device for an electric driving tractor. Background Technology

[0002] With the rapid development of agricultural mechanization and intelligence, electric driving tractors are increasingly widely used in modern agricultural production due to their advantages such as energy saving, environmental protection, and convenient operation. As the core safety component of electric driving tractors, the performance of the braking device directly determines the driving safety and operational stability of the tractor during operation.

[0003] However, the braking system of existing electric driving tractors has a relatively simple structure design. During braking, the contact area between the brake pads and the wheel hub is small, resulting in dispersed braking force. In complex farmland conditions such as muddy roads and steep slopes, problems such as braking lag and slippage are likely to occur. Utility Model Content

[0004] The purpose of this utility model is to provide a braking device for an electric driving tractor, which aims to solve the technical problems in the prior art where the contact area between the brake pads and the wheel hub is small during the braking process, resulting in dispersed braking force and easy braking lag and slippage in complex farmland road conditions such as mud and steep slopes.

[0005] To achieve the above objectives, this utility model provides a braking device for an electric driving tractor, comprising a brake cover, a drive shaft disposed on the outer side of the brake cover, a rotating shaft disposed on the outer side of the drive shaft and located inside the brake cover, a shaped block disposed on the outer side of the rotating shaft, and a push frame rotatably disposed at the other end of the shaped block; an arc-shaped push plate disposed at the other end of the push frame, a mounting plate disposed on the outer side of the arc-shaped push plate, an arc-shaped brake pad disposed on the outer side of the mounting plate, and the brake cover having a through groove adapted to the arc-shaped brake pad.

[0006] The arc-shaped push plate has a guide rod on one side adjacent to the mounting plate, and the brake cover has a sliding groove that slides with the guide rod.

[0007] The rotating shaft has a limiting rod at one end away from the drive shaft, and a limiting sleeve is provided on the outside of the limiting rod, and the limiting sleeve is fixedly connected to the brake cover.

[0008] The limiting rod has a balance bar on its outer side, and the arc-shaped push plate has an auxiliary rod on the side away from the push frame, with the balance bar attached to the auxiliary rod.

[0009] The balance bar has an extension block below it, and an inclined telescopic spring is provided on the outside of the extension block. The other end of the inclined telescopic spring is located on the outside of the push frame.

[0010] Compared with the prior art, this utility model has the following advantages:

[0011] 1. By cooperating with the through groove of the brake cover, the contact surface between the arc-shaped brake pad and the tractor wheel hub is increased, making the braking force more concentrated and effectively improving the braking efficiency.

[0012] 2. The sliding engagement between the guide rod and the sliding groove can stably guide the movement direction of the arc-shaped push plate, ensuring the stability of the arc-shaped brake pad operation. The rotational engagement between the limiting rod and the limiting sleeve ensures the stability of the rotation of the rotating shaft, effectively reducing component wear.

[0013] 3. The inclined telescopic spring can pull the push frame to reset after the braking operation is completed, thereby driving the arc-shaped brake pad to quickly disengage from the wheel hub and reduce the consumption of driving force. Attached Figure Description

Detailed Implementation

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] Please see Figures 1-4 ,in Figure 1 This is a schematic diagram of the structure of a braking device for an electric driving tractor according to this utility model.

[0022] In this embodiment, a brake cover 101 is included. A drive shaft 102 is disposed on the outer side of the brake cover 101, and a rotating shaft 103 is disposed on the outer side of the drive shaft 102, with the rotating shaft 103 located inside the brake cover 101. A shaped block 104 is disposed on the outer side of the rotating shaft 103, and a pusher 105 is rotatably disposed at the other end of the shaped block 104. An arc-shaped push plate 106 is disposed at the other end of the pusher 105, and an mounting plate 107 is disposed on the outer side of the arc-shaped push plate 106. An arc-shaped brake pad 108 is disposed on the outer side of the mounting plate 107, and the brake cover 101 has a through groove 116 adapted to the arc-shaped brake pad 108. The brake cover 101 is provided with bolt mounting... A mounting hole is provided for mounting the brake cover 101 inside the tractor wheel hub. One end of the drive shaft 102 is connected to the motor output end of the electric driving tractor via a coupling, providing a power source for its braking action. The drive shaft 102 drives the rotating shaft 103 to rotate, and the rotating shaft 103 drives the irregular block 104 to rotate synchronously. The irregular block 104 pushes the push frame 105 to rotate around the connection point via a pin. The other end of the push frame 105 generates an outward thrust on the arc-shaped push plate 106, causing the mounting plate 107 to push the arc-shaped brake pad 108 to move outward. The arc-shaped brake pad 108 abuts against the tractor wheel hub through the through groove 116, thereby achieving braking of the tractor.

[0023] The arc-shaped push plate 106 is provided with a guide rod 109 on one side adjacent to the mounting plate 107, and the brake cover 101 has a sliding groove 117 that slides with the guide rod 109. When the arc-shaped push plate 106 moves, it drives the guide rod 109 to move synchronously. The guide rod 109 slides in the sliding groove 117, thereby accurately guiding the movement direction of the arc-shaped push plate 106 and effectively preventing the arc-shaped push plate 106 and the arc-shaped brake pad 108 from deviating.

[0024] Secondly, a limiting rod 110 is provided at one end of the rotating shaft 103 away from the drive shaft 102. A limiting sleeve 111 is provided on the outer side of the limiting rod 110, and the limiting sleeve 111 is fixedly connected to the brake cover 101. The rotating shaft 103 drives the limiting rod 110 to rotate synchronously, and the limiting sleeve 111 restricts the rotation of the limiting rod 110, thereby effectively reducing the wear of the components and improving the service life of the structure.

[0025] Meanwhile, a balance bar 112 is provided on the outer side of the limiting rod 110, and an auxiliary rod 113 is provided on the side of the arc-shaped push plate 106 away from the push frame 105. The balance bar 112 is attached to the auxiliary rod 113. The limiting rod 110 drives the balance bar 112 to rotate, and the balance bar 112 pushes the auxiliary rod 113. The auxiliary rod 113 assists in pushing the arc-shaped push plate 106 to move, effectively improving the braking strength.

[0026] Additionally, an extension block 114 is provided below the balance bar 112, and an inclined telescopic spring 115 is provided on the outer side of the extension block 114. The other end of the inclined telescopic spring 115 is provided on the outer side of the push frame 105. When braking is not applied, the inclined telescopic spring 115 is in a naturally stretched state. The tension of the inclined telescopic spring 115 acts on the push frame 105, so that the arc-shaped push plate 106 and the arc-shaped brake pad 108 are kept in their initial positions, ensuring that the arc-shaped brake pad 108 is inside the brake cover 101, avoiding ineffective friction with the tractor wheel hub. When the braking operation is completed, the inclined telescopic spring 115 assists in the reset of the arc-shaped push plate 106 and the arc-shaped brake pad 108.

[0027] Using the braking device of an electric tractor according to this embodiment, by setting the brake cover 101, the drive shaft 102, and the rotating shaft 103, in specific use, the brake cover 101 is installed inside the tractor wheel hub, and the drive shaft 102 is connected to the motor output end through a coupling. When no braking operation is performed, the inclined telescopic spring 115 pulls the push frame 105 to prevent the arc-shaped brake pad 108 from having ineffective friction with the tractor wheel hub. When braking operation is performed, the drive shaft 102 drives the rotating shaft 103 to rotate, and the rotating shaft 103 simultaneously drives the irregular block 104 and the limiting rod 110 to rotate synchronously. The limiting sleeve 111 ensures the stability of the rotation of the limiting rod 110, and the irregular block 104 drives the push frame 105 to rotate, so that the brake pad 108... The other end of the pusher 105 pushes the arc-shaped push plate 106 to move. At the same time, the limiting rod 110 drives the balance bar 112 to rotate. The balance bar 112 pushes the auxiliary rod 113 to assist the arc-shaped push plate 106 in moving. When the arc-shaped push plate 106 moves, the guide rod 109 slides according to the sliding groove 117 to ensure that the arc-shaped push plate 106 moves axially. The mounting plate 107 pushes the arc-shaped brake pad 108 to move axially. The arc-shaped brake pad 108 brakes the wheel hub through the through groove 116. The overall structure of this braking device is compact and easy to install. It can be directly adapted to the structure of existing electric drive tractors without modifying the tractor. It can effectively ensure the stability of braking force output and avoid the problems of tractor braking lag and slippage.

[0028] The above-disclosed embodiments are merely preferred embodiments of the electric driving tractor braking device of this utility model, and should not be construed as limiting the scope of this utility model. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes according to the claims of this utility model still fall within the scope of this utility model.
