Description

Display device for contact state of finished automobile limiting block

Technical Field

The utility model relates to the field of automobile design, in particular to a display device for a contact state of a complete automobile limiting block.

Background

The light-duty load automotive suspension is mostly the leaf spring suspension, is equipped with the buffer block between leaf spring and frame, and the main objective has three. First, due to the nature and use of cargo, many driving conditions are harsh. The plate spring suspension is mostly adopted, when the suspension is fully loaded, a vehicle runs on a severe road surface, and a plate spring is extremely easy to directly impact a vehicle frame, so that the plate spring is likely to break, and great potential safety hazards are caused. In order to avoid the direct impact of the plate spring on the frame, a buffer block (limiting block) is required to be installed on the plate spring. When the vehicle runs on a severe road surface, the limiting block plays a role in buffering when the plate spring jumps up. And secondly, the added buffer block can play a role of an auxiliary spring, and the rigidity of the whole suspension can be improved. Thirdly, the added buffer blocks can reduce the deformation of the plate spring and are beneficial to the fatigue durability of the plate spring.

Due to the addition of the buffer block, when the plate spring suspension is designed, the clearance between the buffer block and the vehicle frame in an initial state becomes a key parameter. The initial clearance is set to be too large, the buffer block does not work, the plate spring deforms greatly, and the suspension rigidity is not favorably improved and the plate spring is not durable. If the initial gap is too small, the limiting block frequently contacts with the frame or the vehicle body, and the impact feeling is strong.

When the road test of the real vehicle is carried out, an initial limit block gap value is set firstly, then, in the road test of a specific road surface, a driver confirms whether the limit block is contacted or not by feeling, and then, the limit block gap value is adjusted according to the state of the whole vehicle. Because different drivers feel different, the judgment of the contact state of the limiting block is often deviated, and the setting of the gap of the limiting block is not facilitated.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems and provides a display device for the contact state of a limit block of a whole vehicle, which can display the clearance condition of the limit block, improve the judgment on the accuracy of the contact state of the limit block and reduce individual difference. The specific technical scheme is as follows:

a display device for the contact state of a finished automobile limiting block comprises: the display device comprises a battery box, a copper wire, an LED bulb and a metal sheet which are connected in sequence to form a circuit; the metal sheet is arranged on the buffer block; one end of the copper wire is arranged on an upward jumping limit plate of the buffer block; the buffer block is fixed in the middle of the plate spring through a U-shaped bolt, and the bounce limiting plate is fixed on the frame through a bolt.

Further, the U-shaped bolt fixes the plate spring on the axle.

Furthermore, two 5V dry batteries are arranged in the battery box, and the LED bulb is arranged in the cab.

Furthermore, the bounce limiting plate is a metal plate, and the metal sheet and the copper lead are soldered together.

Furthermore, the plate spring is connected to the frame through the lifting lugs and the lug rolling bushings which are respectively arranged at the two ends of the plate spring.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1-2: a display device for the contact state of a whole vehicle limiting block: the display device comprises a battery box 3, a copper wire 9, an LED bulb 10 and a metal sheet 7 which are connected in sequence to form a circuit; the metal sheet 7 is arranged on the buffer block 5; one end of the copper wire 9 is arranged on an upward jumping limit plate 8 of the buffer block 5; the buffer block 5 is fixed in the middle of the plate spring 2 through a U-shaped bolt 4, and the bounce limiting plate 8 is fixed on the frame through a bolt. The U-bolt 4 secures the leaf spring 2 to the vehicle axle. Two 5V dry batteries are arranged in the battery box 3, and the LED bulb 10 is arranged in the cab. The bounce limiting plate 8 is a metal plate, and the metal sheet 7 and the copper lead 9 are soldered together. The plate spring 2 is connected to the frame through the lifting lugs 1 and the rolling lugs 6 which are respectively arranged at two ends.

When the vehicle axle moves upwards, the plate spring 2 and the buffer block 5 are driven to move upwards together. The clearance between the buffer block 5 and the rebound limiting plate 8 is gradually reduced to 0, namely, the contact state is obtained. The top of the buffer block 5 is pasted with a metal sheet 7 which is soldered with a copper lead 9. The bump stopper plate 8 is a metal plate having good conductivity, and is soldered to the copper wire 9. When the plate spring moves upwards, the gap between the buffer block 5 and the upward-jumping limit plate 8 is gradually reduced, the metal sheet 7 is in contact with the upward-jumping limit plate 8 when the gap is 0, and the LED bulb 10 is lightened. When the plate spring moves downwards, the metal sheet 7 is separated from the rebound limiting plate 8, and the LED bulb 10 is turned off. Therefore, the contact state of the buffer block can be directly judged according to the on-off state of the LED bulb 10.

Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
