Description

Technical Field

[0001] The utility model belongs to the field of output shafts, in particular to a lossless transmission steering input shaft. Background Art

[0002] The main function of the output shaft is to convert high-speed, low-torque power into low-speed, high-torque power to meet the needs of car driving. Specifically, it converts the high speed output of the engine into low speed through the reducer. This low-speed power can also be transmitted along the transmission shaft to the driving wheels of the car, enabling it to start the car and provide sufficient driving force.

[0003] Nowadays, most output shafts are integrally formed, and they need to be replaced as a whole if part of them is damaged. In addition, the output shaft generally has a large torque. After long-term use, the middle part of the output shaft will be twisted, causing the output process to jitter and reduce the output efficiency. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides a lossless transmission steering input shaft.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a lossless transmission steering input shaft, comprising a main output shaft and an auxiliary output shaft which are separately arranged, characterized in that: a toothed portion is provided on a side of the main output shaft away from the auxiliary output shaft, and a reinforcement component is provided inside the main output shaft and the auxiliary output shaft;

[0006] The reinforcing component includes at least two limit blocks fixed on the end face of the auxiliary output shaft close to the main output shaft, and at least two limit grooves are opened in the main output shaft. The limit blocks and the limit grooves are both arranged obliquely, and the torque of the output shaft rotation is strengthened by the cooperation of the limit blocks and the limit grooves.

[0007] Optionally, the spiral oblique direction of the limiting groove and the limiting block is opposite to the rotation direction of the input shaft.

[0008] Optionally, a slide groove is provided in the secondary output shaft and the main output shaft, a limit pin is slidably provided in the slide groove, and the limit pin and the slide groove are both square in shape.

[0009] Optionally, a threaded opening is provided on an end surface of the secondary output shaft away from the main output shaft, a threaded pin is threadedly connected in the threaded opening, and the threaded opening is connected to a sliding groove in the secondary output shaft.

[0010] Optionally, a gear is detachably mounted on the outer peripheral side of the secondary output shaft.

[0011] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. Due to the setting of the reinforcement component, the spiral oblique limit block and the limit groove can be set to avoid the twisting phenomenon caused by the torsion between the auxiliary output shaft and the main output shaft when the output shaft rotates, thereby making the transmission efficiency of the output shaft higher and avoiding large jitter.

[0013] 2. The main output shaft and the auxiliary output shaft can also be separately set, so that the auxiliary output shaft or the main output shaft can be replaced separately after the output shaft is damaged, effectively avoiding the waste of the entire replacement.

[0018] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0019] As shown in Figures 1-3, a lossless transmission steering input shaft includes a main output shaft 10 and an auxiliary output shaft 12 which are separately arranged, a gear 13 is detachably installed on the outer peripheral side of the auxiliary output shaft 12, a tooth portion 11 is provided on the side of the main output shaft 10 away from the auxiliary output shaft 12, and a reinforcement component is provided in the main output shaft 10 and the auxiliary output shaft 12. The reinforcement component includes at least two limit blocks 14 fixed on the end face of the auxiliary output shaft 12 on one side close to the main output shaft 10, and at least two limit grooves 17 are opened in the main output shaft 10. The limit blocks 14 and the limit grooves 17 are both obliquely arranged, and the torque of the output shaft rotation is strengthened by the cooperation of the limit blocks 14 and the limit grooves 17. The spiral oblique direction of the limit grooves 17 and the limit blocks 14 is opposite to the direction of rotation of the input shaft.

[0020] A slide groove 18 is provided in the auxiliary output shaft 12 and the main output shaft 10, and a limit pin 16 is slidably provided in the slide groove 18. The limit pin 16 and the slide groove 18 are both square-shaped. Through the setting of the limit pin 16, the main output shaft 10 and the auxiliary output shaft 12 can be limited to prevent them from rotating and disengaging. A threaded opening is provided on the end surface of the auxiliary output shaft 12 away from the main output shaft 10, and a threaded pin 15 is threadedly connected in the threaded opening, and the threaded opening is connected to the slide groove 18 in the auxiliary output shaft 12.

[0021] When in use, the limit block 14 can be embedded in the limit groove 17, and then the limit pin 16 can be inserted to connect the limit pin 16 to the auxiliary output shaft 12 and the main output shaft 10. At this time, the limit pin 16 can be used to limit the auxiliary output shaft 12 and the main output shaft 10 from rotating and disconnecting. Then, the threaded pin 15 can be screwed on to prevent the limit pin 16 from slipping off. Since the oblique direction of the thread of the limit block 14 is opposite to that of the output shaft, when the output shaft rotates, the torque between the auxiliary output shaft 12 and the main output shaft 10 can be avoided from causing distortion, thereby making the transmission efficiency of the output shaft higher.

[0022] When one of the main output shaft 10 or the auxiliary output shaft 12 is damaged and needs to be replaced, the threaded pin 15 needs to be rotated and removed, and then the limit pin 16 is poured out. At this time, the auxiliary output shaft 12 can be rotated, and the limit block 14 can be screwed out from the limit groove 17. Then the auxiliary output shaft 12 or the main output shaft 10 can be replaced separately, effectively avoiding the waste of the entire replacement.

[0023] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
