Description

Technical Field

[0002] The torsion shaft is an important component in the mechanical transmission system that bears torque and transmits power. It has a strong ability to withstand torque and is often used in machines that transmit large torque. It can transmit power and speed, and together with the vehicle drive shaft, it forms a drive structure and is often used in machines that require angular displacement transmission; the rotary torsion shaft refers to a straight shaft with torsional elasticity, which is often installed between the vehicle body and the frame to resist the lateral rolling vibration of the vehicle body.

[0003] The rubber torsion shaft is a type of torsion shaft. Its principle is to use four cylindrical rubber rods inserted between a square torsion bar and a square sleeve, and the torsion bar rotates to squeeze the rubber rods to achieve a shock-absorbing and buffering effect.

[0036] For example, see Figure 1-14 , the present invention provides the following technical solutions:

[0037] A vehicle torsion shaft assembly, specifically, comprises a square sleeve 1 with an opening at one end; a sealing cover 2 is fixed to the open end of the square sleeve 1; a square torsion bar 3 is rotatably arranged between the sealing cover 2 and the sealed end of the square sleeve 1; a plurality of rotating holes 4 are provided on the side of the sealing cover 2 and the sealed end of the square sleeve 1; an elastic component 5 is rotatably arranged between two relatively rotating holes 4; the elastic component 5 comprises an elastic part 6 rotatably arranged in the corresponding rotating hole 4; a plurality of supporting parts 7 slidably matched with the inner wall of the square sleeve 1 are uniformly rotatably arranged on the elastic part 6; the elastic part 6 comprises a rotating shaft 8; a plurality of elastic rubber rods 9 are uniformly fixed to the rotating shaft 8; spiral grooves 10 are provided on the circumferential side of the rotating shaft 8 near its two ends; sliding parts 11 slidably matched with the corresponding spiral grooves 10 are slidably arranged on the square sleeve 1 and the sealing cover 2.

[0038] Working principle of the first embodiment:

[0039] By controlling the two sliding parts 11 to slide along the square sleeve 1 and the sealing cover 2 respectively, and cooperating with the guidance of the corresponding spiral groove 10, the groups of rotating shafts 8 are driven to rotate synchronously, thereby driving the elastic rubber rod 9 to rotate synchronously, so as to continuously replace the extrusion position of the elastic rubber rod 9 and the square torsion bar 3, avoiding a certain position of the elastic rubber rod 3 from being squeezed and rubbed for a long time, and improving the service life of the elastic rubber rod 9.

[0040] For example 2, please refer to Figure 1-14, the second embodiment makes the following improvements on the basis of the first embodiment. Specifically, a mounting frame 12 is symmetrically fixedly installed on the top of the square sleeve 1; an axial hole 13 is provided on the sealing end of the square sleeve 1 and the side of the sealing cover 2; a rotating rod 58 rotatably matched with the corresponding axial hole 13 is fixed at both ends of the square torsion bar 3; a square groove 14 is provided at the end of the rotating rod 58; a sleeve 15 is rotatably provided on the sealing end of the square sleeve 1 and the side of the sealing cover 2; a first connecting flange 16 is fixed to the end of the sleeve 15; a swing arm 17 is clamped on the square groove 14; a connecting shaft sleeve 18 sleeved on the corresponding rotating rod 58 is fixed at one end of the swing arm 17; a clamping column 19 clamped with the square groove 14 is fixed inside the connecting shaft sleeve 18; a second connecting flange 20 fixedly connected to the first connecting flange 16 by fastening bolts is fixed at the end of the connecting shaft sleeve 18.

[0041] An annular groove 21 is formed between two adjacent elastic rubber rods 9 on the rotating shaft 8; the supporting part 7 includes a fixing ring 22 rotatably arranged in the annular groove 21; a supporting rod 23 is fixed to the side surface of the fixing ring 22; and an angle plate 24 that slides with the inner wall of the square sleeve 1 is fixed to the end of the supporting rod 23.

[0042] Working principle of the second embodiment:

[0043] By placing the square torsion bar 3 and each group of elastic components 5 into the square sleeve 1, and fixing the sealing cover 2 to the open end of the square sleeve 1 by tightening bolts, the square torsion bar 3 is rotatably arranged between the sealing cover 2 and the sealed end of the square sleeve 1, and each group of rotating shafts 8 is rotatably arranged in the corresponding rotating holes 4. At this time, each group of elastic rubber rods 9 is pressed tightly on the square torsion bar 3. At the same time, each group of corner plates 24 are placed on the adjacent inner wall of the square sleeve 1 to support the rotating shaft 8 and improve the stability of the elastic component 5.

[0044] After completing the assembly of the square torsion bar 3 and each group of elastic components 5, the assembly of the swing arm 17 is completed by inserting the clamping column 19 into the square groove 14 and tightening the bolts to fix the second connecting flange 20 on the first connecting flange 16, so that the rotation and swinging of the swing arm 17 can drive the synchronous rotation of the sleeve 15 and the rotating rod 58.

[0045] For example 3, please refer to Figure 1-14 The third embodiment is improved on the basis of the second embodiment as follows. Specifically, the sliding part 11 includes a sliding frame 25 which is slidably arranged on the sealing cover 2 and the square sleeve 1 respectively; a plurality of extension plates 26 are evenly arranged on the side of the sliding frame 25; an ear rod 27 is fixed on the side of the extension plate 26; and a guide ball 28 which is slidably matched with the spiral groove 10 is fixed on the end of the ear rod 27.

[0046] A support plate 29 is symmetrically fixed to the bottom surface of the square sleeve 1; a rotating tube 30 is rotatably provided on the side surface of the support plate 29; a reciprocating screw rod 31 coaxially therewith is fixed to the end of the rotating tube 30; an ear plate 32 is fixed to the bottom surface of the sliding frame 25; a sliding sleeve 33 adapted to the reciprocating screw rod 31 is fixed to the bottom end of the ear plate 32; a connecting rod 34 is rotatably provided inside the rotating tube 30 and the reciprocating screw rod 31; a driven sprocket 35 is fixed to one end of the connecting rod 34; a driving sprocket 36 is fixed to the side surface of the connecting sleeve 18; a chain 37 is provided for meshing transmission between the driving sprocket 36 and the driven sprocket 35; a connecting tube 38 is fixed to one end of the reciprocating screw rod 31; a ratchet ring 39 is fixed to the side surface of the connecting rod 34; a pawl 40 adapted to the ratchet ring 39 is rotatably provided on the inner side surface of the connecting tube 38; an arc spring 41 is fixedly connected between the pawl 40 and the inner side surface of the connecting tube 38.

[0047] Working principle of the third embodiment:

[0048] A slider matched with the reciprocating screw 31 is arranged inside the sleeve 33. The reciprocating screw 31 is a form of a three-dimensional cam pair, which is represented by two thread grooves with the same pitch and opposite rotation directions, and the two ends are connected by a transition curve. Through the rotation of the reciprocating screw 31, the side of the spiral groove pushes the slider placed in the spiral groove to perform axial reciprocating motion.

[0049] When the vehicle wheels swing up and down when driving on an uneven road surface, the wheels drive the swing arm 17 to swing up and down and rotate, thereby driving the square torsion bar 3 to rotate back and forth inside the square sleeve 1. When the swing arm 17 rotates upward counterclockwise, the square torsion bar 3 and the driving sprocket 36 are driven to rotate counterclockwise to squeeze each group of elastic rubber rods 9. Since the elastic rubber rods 9 are made of elastic rubber material, it is convenient for the elastic rubber rods 9 to buffer and reset the torque of the rotation of the square torsion bar 3, thereby facilitating the reduction of the bumpy feeling of the vehicle. Through the transmission of the chain 37, the rotation of the driven sprocket 35 is driven. At the same time, through the ratchet ring 39, the pawl 40 and the elastic force of the arc spring 41, the pawl 40 is driven to be stuck in the ratchet ring 39, so that the connecting tube 38 and the reciprocating screw rod 31 rotate synchronously counterclockwise, thereby driving the sliding part 11 to slide, so that the corresponding guide ball 28 slides along the corresponding spiral groove 10, thereby driving each group of rotating shafts 8 together with the elastic rubber rods 9 to rotate.

[0050] When the swing arm 17 rotates clockwise downward, it drives the square torsion bar 3 together with the driving sprocket 36 to rotate clockwise to squeeze each group of elastic rubber rods 9. At this time, the pawl 40 does not restrict the ratchet ring 39, and the connecting rod 34 rotates freely inside the reciprocating screw rod 31 and the rotating tube 30, while the reciprocating screw rod 31 does not rotate with the rotation of the connecting rod 34, that is, in this process, each group of elastic rubber rods 9 will not rotate autonomously.

[0051] During the whole process, the elastic rubber rod 9 can only rotate in one direction, so as to continuously change the extrusion position between the elastic rubber rod 9 and the square torsion bar 3, thereby preventing a certain position of the elastic rubber rod 3 from being extruded and rubbed for a long time, and improving the service life of the elastic rubber rod 9.

[0052] Example 4, please refer to Figure 1-14 The fourth embodiment is improved on the basis of the third embodiment as follows. Specifically, both ends of the square sleeve 1 are fixedly connected with a sealing cover 42 by fastening bolts; the sealing cover 42 includes two symmetrically arranged cover bodies 43; the two cover bodies 43 are fixedly connected by fastening bolts; the surface of the cover body 43 is provided with an avoidance groove 57 that is plugged with the support plate 29, and the side thereof is provided with a slide groove 44; a guide box 45 is provided on the inner bottom surface of one cover body 43; the two cover bodies 43 are fixedly installed on the square sleeve 1 by fastening bolts.

[0053] A gear 46 is fixed to the other end of the connecting rod 34; an exhaust pipe 47 and an air inlet pipe 48 are symmetrically connected and arranged on the inner bottom surface of the square sleeve 1; the ends of the air inlet pipe 48 and the exhaust pipe 47 are fixedly connected to a ventilation part 49; the ventilation part 49 includes a toothed plate 50 slidably arranged in the guide box 45; the toothed plate 50 is meshed with the gear 46; an extension block 51 slidably matched with the slide groove 44 is fixed to the top of the toothed plate 50; a U-shaped rod 52 is fixed to the bottom surface of the extension block 51; the ventilation part 49 also includes a piston cylinder 53; an air supply pipe 54 is connected and arranged at the end of the piston cylinder 53, and an ear tube 55 is connected and arranged near its end on the peripheral side surface; the two air supply pipes 54 are fixedly connected to the air inlet pipe 48 and the exhaust pipe 47 respectively; a piston plate 56 slidably matched with the piston cylinder 53 is fixed to the end of the U-shaped rod 52; and a one-way valve is arranged on the air supply pipe 54 and the ear tube 55.

[0054] Working principle of the fourth embodiment:

[0055] One-way valves are provided on the air supply pipe 54 and the ear tube 55 on the ventilation part 49 connected to the exhaust pipe 47, so that the hot air in the corresponding piston cylinder 53 can only be discharged through the ear tube 55, and the hot air in the square sleeve 1 can only be drawn into the corresponding piston cylinder 53 through the air supply pipe 54; one-way valves are provided on the air supply pipe 54 and the ear tube 55 on the ventilation part 49 connected to the intake pipe 48, so that the cold air in the corresponding piston cylinder 53 can only be discharged into the square sleeve 1 through the air supply pipe 54, and the external cold air can only be drawn into the corresponding piston cylinder 53 through the ear tube 55.

[0056] When the wheels of the vehicle swing up and down when driving on an uneven road surface, the wheels drive the swing arm 17 to swing up and down, thereby driving the gear 46 to reciprocate and reverse, thereby driving the toothed plate 50 to lift and reciprocate along the guide box 45, thereby driving the piston plate 56 to lift and slide in the corresponding piston cylinder 53, thereby realizing air circulation between the inside of the square sleeve 1 and the external cold air, discharging the heat generated by the friction between the square torsion bar 3 and the elastic rubber rod 9, preventing the internal temperature of the square sleeve 1 from being too high and causing damage to the elastic rubber rod 9, and further improving the service life of the elastic rubber rod 9.

[0057] Two sets of covers 43 are installed at both ends of the square sleeve 1 by tightening bolts to cover the components. The side of the cover 43 is provided with an avoidance hole that rotates with the connecting sleeve 18. The setting of the cover 43 protects the components and prevents the components from being damaged during the driving of the vehicle.
