Description

Technical Field

[0001] The utility model relates to the technical field of steering yokes, in particular to a multifunctional integrated automobile steering yoke. Background Art

[0002] Automobile steering yoke is commonly used in automobile chassis steering system. One end of the yoke is connected to the steering rod, receiving steering instructions and transmitting steering force; the other end is connected to the wheel hub, driving the wheel to turn. It is a force transmission hub that can effectively ensure accurate and smooth steering, and provide support for braking components. It plays a key role in maintaining vehicle driving stability, safety and controllability.

[0003] In actual work, the combination of the steering yoke, steering rod and brake components of the existing automobile can basically meet the basic requirements for automobile steering, but there are still the following problems:

[0004] During vehicle braking, since the steering yoke is usually connected to the brake caliper, when the brake caliper clamps the brake disc, a large amount of heat is generated and conducted to the steering yoke and nearby components. The temperature of the yoke body rises rapidly, and the high temperature remains near the yoke, resulting in a decrease in braking effect, affecting the braking effect, and at the same time causing severe vibration. For this reason, the present application provides a multifunctional integrated automobile steering yoke to meet the needs. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and provide a multifunctional integrated automobile steering yoke.

[0006] In order to achieve the above object, the utility model adopts the following technical solution: a multifunctional integrated automobile steering yoke, comprising a yoke head, the bottom of which is provided with a wheel hub connecting end;

[0007] A heat dissipation assembly is provided at the bottom of the yoke head, and the heat dissipation assembly is composed of a sleeve fixedly connected to the bottom of the yoke head, and the outer surface of the sleeve is provided with multiple groups of grooves;

[0008] The shock absorbing assembly is used to assist the heat dissipation assembly in heat dissipation. The shock absorbing assembly consists of a fixed ring fixedly connected to the side of the hub connection end;

[0009] Wherein, both sides of the outer surface of the sleeve are slidably connected with connecting pieces, the side surface of one end of the connecting piece is fixedly connected with a sliding piece, and the side surface of the sliding piece is fixedly connected with a rubber piston.

[0010] As a preferred embodiment, the inner cavity of the sleeve is fixedly connected to a fixing rod, the side of the bottom of the fixing rod is fixedly connected to a support ring, the top of the support ring is fixedly connected to a first spring piece, and the end of the first spring piece away from the support ring is fixedly connected to the bottom of the rubber piston.

[0011] The technical effect of adopting the above technical solution is: by providing the first spring sheet, the rubber piston can be supported, effectively improving a certain stability, and at the same time, providing a certain amount of additional auxiliary stress to the rubber piston when it is reset.

[0012] As a preferred embodiment, both sides of the sliding member are fixedly connected with second elastic pieces, and one end of each of the two second elastic pieces is fixedly connected with a sliding block.

[0013] The technical effect of adopting the above technical solution is that, by providing the second elastic sheet, the rubber piston can be buffered when it is subjected to lateral stress.

[0014] As a preferred embodiment, a limiting groove is provided in the inner cavity of the sleeve, one end of the sliding member extends to the inner cavity of the limiting groove, and one end of the sliding member is slidably connected to the inner cavity of the limiting groove.

[0015] The technical effect of adopting the above technical solution is that the movement trajectory of the sliding member can be limited by setting the limiting groove.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are:

[0017] A seal is provided on the side of the rubber piston, and heat-conducting blocks are provided on both sides of the bottom of the sleeve. One end of the heat-conducting block is slidably connected to the cooling fins provided at the bottom of the disc. During installation, the yoke head and the fixing ring are first installed at the bottom of the steering rod, and then the hub connecting end is fixedly connected to the side of the wheel hub. After the installation is completed, during the normal driving of the car, the heat generated by the brake can be dissipated through the cooperation of the heat-conducting block and the groove. When the braking increases, the heat rises rapidly, accompanied by a certain vibration. When the temperature rises, the heat is transferred to the sleeve through the hub connecting end, which can prompt the inner cavity of the sleeve to heat up rapidly. At this time, a certain vibration occurs at the wheel hub connection. Vibration can cause the hub connection end to move up and down, thereby driving the sliding part to move up and down through the connecting part, and then achieving the effect of driving the rubber piston to move. When the rubber piston moves downward, the pressure in the inner cavity of the sleeve increases, thereby prompting the hot air to be discharged through the inner cavity of the groove. Similarly, when the rubber piston moves upward, the pressure in the inner cavity of the sleeve becomes smaller, thereby prompting the rapid exchange of air inside and outside. Through the cooperation of the rubber piston and the heat-conducting block arranged at the bottom of the sleeve, the steering yoke body can be assisted in cooling down, thereby effectively improving the cooling speed of the steering yoke and avoiding the reduction of braking effect due to excessive temperature.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1 - Figure 3 As shown, this embodiment provides a technical solution: a multifunctional integrated automobile steering yoke, comprising a yoke head 1, a wheel hub connection end 11 being provided at the bottom of the yoke head 1;

[0028] The heat dissipation component 3 is arranged at the bottom of the yoke head 1. The heat dissipation component 3 is composed of a sleeve 31 fixedly connected to the bottom of the yoke head 1. The outer surface of the sleeve 31 is provided with multiple groups of grooves 310;

[0029] The shock absorbing assembly 2 is used to assist the heat dissipation assembly 3 in heat dissipation. The shock absorbing assembly 2 is composed of a fixing ring 21 fixedly connected to the side of the hub connecting end 11;

[0030] Among them, both sides of the outer surface of the sleeve 31 are slidably connected with connecting parts 32, the side of one end of the connecting part 32 is fixedly connected to the sliding part 33, the side of the sliding part 33 is fixedly connected to the rubber piston 34, the inner cavity of the sleeve 31 is fixedly connected to the fixing rod 35, the side of the bottom of the fixing rod 35 is fixedly connected to the supporting ring 36, the top of the supporting ring 36 is fixedly connected to the first elastic piece 37, the end of the first elastic piece 37 away from the supporting ring 36 is fixedly connected to the bottom of the rubber piston 34, the bottom of the inner cavity of the sleeve 31 is fixedly connected to the fixing block 312, and the side of the rubber piston 34 is provided with a sealing member. Heat conducting blocks are provided on both sides of the bottom of the sleeve 31, and one end of the heat conducting block is slidably connected to the heat dissipation fins provided at the bottom of the vehicle disc. During installation, the yoke head 1 and the fixing ring 21 are first installed at the bottom of the steering rod, and then the hub connecting end 11 is fixedly connected to the side of the wheel hub. After installation, during normal driving of the car, the heat generated by braking can be dissipated through the cooperation of the heat conducting block and the groove 310. When the braking increases, the heat rises rapidly, accompanied by a certain vibration. When the temperature rises, the heat is transferred to the sleeve 31 through the hub connecting end 11, so that The inner cavity of the sleeve 31 is rapidly heated up. At this time, a certain vibration occurs at the wheel connection, which can prompt the hub connection end 11 to move up and down, thereby driving the sliding member 33 to move up and down through the connecting member 32, and then achieving the effect of driving the rubber piston 34 to move. When the rubber piston 34 moves downward, the pressure in the inner cavity of the sleeve 31 increases, thereby prompting the hot air to be discharged through the inner cavity of the groove 310. Similarly, when the rubber piston 34 moves upward, the pressure in the inner cavity of the sleeve 31 becomes smaller, thereby prompting the internal and external air to exchange quickly, and through the rubber piston 34 Cooperating with the heat-conducting block provided at the bottom of the sleeve 31, it is possible to achieve the effect of auxiliary cooling of the steering yoke body, effectively improve the cooling speed of the steering yoke, and avoid the reduction of the braking effect due to excessive temperature. During the movement of the rubber piston 34, by providing a fixing rod 35, the movement trajectory of the rubber piston 34 can be limited to avoid the position of the rubber piston 34 from being offset and causing damage. When the rubber piston 34 moves downward, the first spring piece 37 is compressed, thereby being able to buffer the vibration to a certain extent, and effectively improving the stability of the movement of the rubber piston 34.

[0031] A step further, such as Figure 2 and Figure 3As shown: the bottom of the fixing ring 21 is fixedly connected with an elastic member 22, the inner cavity of the hub connecting end 11 is fixedly connected with a thick spring piece 24, one end of the thick spring piece 24 is fixedly connected to the bottom of the sleeve 31, one end of the elastic member 22 is fixedly connected to a collar 23, the side of the collar 23 is fixedly connected to the side of the sleeve 31, and a damping plate is provided on the top of the collar 23; by arranging the elastic member 22 and the thick spring piece 24, the stress generated during vibration can be buffered to avoid sudden changes in stress on the sleeve 31, which may cause damage. At the same time, when the hub connecting end 11 moves up and down along the outer surface of the sleeve 31, it can provide a certain amount of additional stress for its reset, which helps to improve the stability of the operation of the heat dissipation component 3.

[0032] When braking during the steering process, since the steering yoke is in a rotating state as a whole, the force on the rubber piston 34 changes, resulting in a certain offset, such as Figure 4 As shown: In this solution, second spring pieces 38 are fixedly connected to both sides of the sliding member 33, and one end of the two second spring pieces 38 is fixedly connected to a sliding block 39. A limiting groove 311 is provided in the inner cavity of the sleeve 31, and one end of the sliding member 33 extends to the inner cavity of the limiting groove 311. One end of the sliding member 33 is slidably connected to the inner cavity of the limiting groove 311. By providing the second spring piece 38, the lateral stress generated by braking during the steering process can be buffered to avoid excessive changes in the lateral stress of the rubber piston 34, which may cause damage. By providing the sliding block 39, the sliding member 33 and the rubber piston 34 can be assisted in movement. By providing the limiting groove 311, the movement trajectory of the sliding block 39 can be limited.

[0033] Working principle:

[0034] like Figure 1-4 As shown:

[0035] During use: first install the yoke head 1 and the fixing ring 21 at the bottom of the steering rod, and then fix the hub connecting end 11 to the side of the wheel hub. After the installation is completed, during the normal driving of the car, the heat generated by braking can be dissipated through the cooperation of the heat conductive block and the groove 310. When braking, the heat rises rapidly, accompanied by a certain vibration. At this time, the temperature rises, and the heat is transferred to the sleeve 31 through the hub connecting end 11, which can prompt the air in the inner cavity of the sleeve 31 to heat up rapidly. At this time, a certain vibration occurs at the wheel hub connection, prompting the hub connecting end 11 to move up and down, thereby driving the sliding part 33 to move up and down through the connecting part 32, and then achieving the effect of driving the rubber piston 34 to move. When the rubber piston 34 moves downward, the pressure in the inner cavity of the sleeve 31 increases The rubber piston 34 is large, thereby promoting the discharge of hot air through the inner cavity of the groove 310. Similarly, when the rubber piston 34 moves upward, the pressure in the inner cavity of the sleeve 31 becomes smaller, thereby promoting the rapid exchange of air inside and outside. The rubber piston 34 and the heat-conducting block arranged at the bottom of the sleeve 31 cooperate with each other, thereby achieving the effect of auxiliary cooling of the steering yoke body. When the rubber piston 34 moves downward, the first elastic piece 37 is compressed, thereby being able to buffer the vibration to a certain extent, effectively improving the stability of the movement of the rubber piston 34. By providing the elastic member 22 and the thick elastic piece 24, the stress generated when vibration occurs can be buffered. At the same time, when the hub connecting end 11 moves up and down along the outer surface of the sleeve 31, it can provide a certain amount of additional stress for its reset, which helps to improve the stability of the operation of the heat dissipation component 3.
