Description

Technical Field

[0001] This utility model belongs to the technical field of drive axle limiting structure, specifically relating to a drive axle limiting structure. Background Technology

[0002] The drive axle is a component of a car. It generally consists of a final drive, differential, wheel drive system, and drive axle housing. The main function of the drive axle is to add a transmission device to the drive wheel axle, converting the engine output into wheel power output to drive the vehicle. The drive axle can also adjust the speed of the drive tires and improve the vehicle's driving stability and handling by controlling the differential.

[0003] Traditional loader chassis and drive axle mounting limit structures on the market mostly involve welding limit blocks onto the chassis before and after the drive axle mounting area. This prevents the bolts connecting the drive axle and the chassis from loosening and breaking due to shearing, thus avoiding greater losses.

[0004] Currently, as vehicles operate for extended periods, the limiting structures welded to the frame may detach from the frame after prolonged vibration. There is no corresponding warning mechanism at present, and users cannot detect the detachment in time. This can easily lead to displacement of the drive axle, causing damage to the drive axle and resulting in losses for the user. It also poses a risk of traffic accidents.

[0005] Therefore, it is necessary to provide a drive axle limiting structure to address the aforementioned technical problems.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] The purpose of this utility model is to provide a drive axle limiting structure that can solve the problem that the upper limit structure of the vehicle frame cannot be detected in time after it is disengaged, causing losses to the user and increasing the risk of traffic accidents.

[0008] To achieve the above objectives, a specific embodiment of the present invention provides a drive axle limiting structure, comprising: a frame body, a protection mechanism, and a pair of warning mechanisms;

[0009] A limiting structure body is fixedly installed on the frame body, and a drive axle body is provided on the lower side of the frame body;

[0010] Warning mechanisms are fixedly installed on both sides of the limiting structure body. The warning mechanism includes a follower rack, a follower gear on the lower side of the follower rack, a follower cam on one side of the follower gear, and a trigger warning device on the upper side of the follower cam.

[0011] A safety mechanism is provided on the side of the follower gear away from the follower cam.

[0012] In one or more embodiments of this utility model, the limiting structure body is matched with the drive axle body, which facilitates the limiting structure body to limit the position of the drive axle body, improves the stability of the drive axle body, and reduces the probability of the drive axle body deviating.

[0013] The trigger warning device is fixedly connected to the frame body, which can fix the position of the trigger warning device, so that the rotation of the follower cam can better trigger the trigger warning device, making the trigger warning device more stably triggered and improving the stability of the trigger warning device.

[0014] In one or more embodiments of this utility model, the follower cam is matched with the trigger alarm, so that the rotation of the follower cam can trigger the trigger alarm, making the trigger alarm more sensitive.

[0015] The follower rack is matched with the follower gear. The follower rack can generate displacement after the limiting structure body and the frame body are separated. When the follower rack generates displacement, the follower gear is driven by the follower rack and will rotate synchronously.

[0016] In one or more embodiments of this utility model, a transmission synchronizing rod is fixedly installed inside the follower gear, which plays a transmission role and can transmit the rotation of the follower gear to the follower cam and the toothed ratchet. At the same time, the transmission synchronizing rod can fix the position of the follower gear, thereby improving the stability of the follower gear.

[0017] In one or more embodiments of this utility model, a pair of balance frames are installed between the transmission synchronizing rod and the frame body, which can restrict the position of the transmission synchronizing rod, improve the stability of the transmission synchronizing rod, improve the balance of the transmission synchronizing rod, and make the follower gear better driven by the follower rack.

[0018] In one or more embodiments of this utility model, balance limit blocks are fixedly installed at both ends of the transmission synchronizing rod, which can limit the transmission synchronizing rod, reduce the possibility of displacement of the transmission synchronizing rod, improve the stability of the transmission synchronizing rod, and ensure the precision between the follower gear and the follower rack.

[0019] In one or more embodiments of this utility model, the protection mechanism includes a toothed ratchet, which can be rotated by the transmission synchronization rod and can be stopped by the engagement of the engaging teeth. It can provide a certain degree of protection after the limiting structure body falls off, improve the stability of the limiting structure body, and provide time for the user to stop and check.

[0020] The transmission synchronization rod is set through the follower gear, follower cam, balance frame and toothed ratchet, and can synchronize the rotation of the follower gear, follower cam and toothed ratchet.

[0021] In one or more embodiments of this utility model, the upper side of the toothed ratchet is provided with engaging teeth, which can fix the position of the toothed ratchet, reduce the possibility of the toothed ratchet rotating, and ensure that even if the limiting structure body is displaced, it will be within a certain limit, thereby improving the protection effect on the drive axle body.

[0022] The toothed ratchet matches the engaging teeth, allowing the engaging teeth to better restrict the rotation of the toothed ratchet.

[0023] In one or more embodiments of this utility model, a limiting shaft is provided inside the engaging tooth, which provides an axis for the rotation of the engaging tooth, so that the rotation of the engaging tooth can be performed around the limiting shaft;

[0024] The limiting shaft is fixedly connected to the frame body, which improves the stability of the limiting shaft and thus improves the stability of the engaging teeth.

[0025] In one or more embodiments of this utility model, a rotary spring is installed between the engaging teeth and the limiting shaft, so that the engaging teeth and the toothed ratchet are always in contact, and the engaging teeth better engage the toothed ratchet.

[0026] Compared with the prior art, the drive axle limiting structure of this utility model, through the setting of corresponding mechanisms, can provide timely warning after detaching from the vehicle frame, enabling users to notice in time, reducing the possibility of drive axle displacement, reducing damage to the drive axle, reducing damage to the user, and also reducing the occurrence of traffic accidents.

Detailed Implementation

[0036] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0037] like Figures 1 to 6 As shown, a drive axle limiting structure in one embodiment of the present invention includes: a frame body 1, a protection mechanism 3, and a pair of warning mechanisms 2.

[0038] like Figures 1 to 5 As shown, a limiting structure body 101 is fixedly installed on the frame body 1, and a drive axle body 102 is provided on the lower side of the frame body 1. Warning mechanisms 2 are fixedly installed on both sides of the limiting structure body 101. The warning mechanism 2 includes a follower rack 201, which can follow the displacement of the limiting structure body 101 and can drive the follower rack 201 to rotate after the limiting structure body 101 is detached from the frame body 1.

[0039] In addition, a follower gear 202 is provided on the lower side of the follower rack 201, which can be driven by the follower rack 201 to rotate, thus playing a transmission role.

[0040] In addition, a follower cam 203 is provided on one side of the follower gear 202, which can rotate synchronously with the rotation of the transmission synchronization rod 205. The rotation can trigger the trigger alarm 204. The trigger alarm 204 is provided on the upper side of the follower cam 203, which can sound an alarm after being triggered to remind the user.

[0041] like Figures 1 to 6 As shown, the limiting structure body 101 is matched with the drive axle body 102, which facilitates the limiting structure body 101 to limit the position of the drive axle body 102, improves the stability of the drive axle body 102, and reduces the probability of the drive axle body 102 deviating.

[0042] The trigger warning device 204 is fixedly connected to the frame body 1, which can fix the position of the trigger warning device 204, so that the rotation of the follower cam 203 can better trigger the trigger warning device 204, making the trigger warning device 204 more stably triggered and improving the stability of the trigger warning device 204.

[0043] like Figures 1 to 6 As shown, the follower cam 203 is matched with the trigger alarm 204, so that the rotation of the follower cam 203 can trigger the trigger alarm 204, making the alarm of the trigger alarm 204 more sensitive.

[0044] In addition, the follower rack 201 is matched with the follower gear 202. The follower rack 201 can generate displacement after the limiting structure body 101 is separated from the frame body 1. When the follower rack 201 generates displacement, the follower gear 202 is driven by the follower rack 201 and will rotate synchronously.

[0045] like Figures 1 to 5 As shown, a transmission synchronizing rod 205 is fixedly installed inside the follower gear 202, which plays a transmission role. It can transmit the rotation of the follower gear 202 to the follower cam 203 and the toothed ratchet 301. At the same time, the transmission synchronizing rod 205 can fix the position of the follower gear 202, thereby improving the stability of the follower gear 202.

[0046] like Figures 1 to 4 As shown, a pair of balance frames 206 are installed between the transmission synchronizer 205 and the frame body 1, which can restrict the position of the transmission synchronizer 205, improve the stability of the transmission synchronizer 205, improve the balance of the transmission synchronizer 205, and make the follower gear 202 better driven by the follower rack 201.

[0047] like Figures 1 to 6As shown, balance limit blocks 207 are fixedly installed at both ends of the transmission synchronizing rod 205, which can limit the transmission synchronizing rod 205, reduce the possibility of displacement of the transmission synchronizing rod 205, improve the stability of the transmission synchronizing rod 205, and ensure the precision between the follower gear 202 and the follower rack 201.

[0048] like Figures 1 to 4 As shown, a safety mechanism 3 is provided on the side of the follower gear 202 away from the follower cam 203. The safety mechanism 3 includes a toothed ratchet 301, which can be rotated by the transmission synchronizing rod 205 and can be stopped by the engagement of the engaging teeth 302. It can provide a certain degree of protection after the limit structure body 101 falls off, improve the stability of the limit structure body 101, and provide time for the user to stop and check.

[0049] The transmission synchronization rod 205 is installed through the follower gear 202, follower cam 203, balance frame 206 and toothless ratchet 301, and can synchronize the rotation of the follower gear 202, follower cam 203 and toothless ratchet 301.

[0050] like Figures 1 to 4 As shown, the upper side of the toothed ratchet 301 is provided with a locking tooth 302, which can fix the position of the toothed ratchet 301, reduce the possibility of the toothed ratchet 301 rotating, and ensure that even if the limiting structure body 101 is displaced, it will be within a certain limit, thus improving the protection effect on the drive axle body 102.

[0051] In addition, the toothed ratchet 301 is matched with the engaging tooth 302, so that the engaging tooth 302 can better restrict the rotation of the toothed ratchet 301.

[0052] like Figures 1 to 5 As shown, the engaging tooth 302 is provided with a limiting shaft 303, which provides an axis for the rotation of the engaging tooth 302, so that the rotation of the engaging tooth 302 can be performed around the limiting shaft 303.

[0053] In addition, the limiting shaft 303 is fixedly connected to the frame body 1, which improves the stability of the limiting shaft 303, and thus improves the stability of the engagement gear 302.

[0054] like Figures 1 to 4 As shown, a rotary spring 304 is installed between the engaging tooth 302 and the limiting shaft 303, so that the engaging tooth 302 and the toothed ratchet 301 are always in contact, so that the engaging tooth 302 can better engage the toothed ratchet 301.

[0055] In practical use, when the frame body 1 is subjected to long-term vibration, the limiting structure body 101 may detach from the frame body 1 and shift. At this time, the follower rack 201 will be driven by the limiting structure body 101 to shift and drive the follower gear 202 to rotate. Through the transmission of the transmission synchronizing rod 205, it can be converted into the rotation of the follower cam 203 and trigger the trigger alarm 204 to generate an alarm. However, the user needs a certain amount of time to stop and check. In order to reduce the displacement distance of the limiting structure body 101, the engaging tooth 302 will engage with the toothed ratchet 301, which can limit the sliding of the follower rack 201 and thus limit the displacement distance of the limiting structure body 101.

[0056] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0057] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
