Description

External wear indicating device for drum-type axle

Technical Field

The utility model relates to an axle technical field, in particular to an external wear indicating device for drum-type axle.

Background

With the rapid development of the automobile industry in China, the requirements of people on the safety, comfort and economy of vehicles are higher and higher. The whole integration is realized on the premise of not reducing the bearing capacity by optimizing the structure and reasonably using new materials and new technologies from the basic design.

The brake system is an important component for ensuring the running safety of the automobile. In order to ensure the operation reliability of the braking performance of the automobile; when the brake pad is close to the limit, the alarm sound reminds the driver to eliminate the brake fault, which is favorable for driving safety; avoiding possible traffic accidents. When doing some axle maintenances, the axle maintains needs dismouting axle wheel hub assembly, and the operation is more troublesome consuming time many with high costs. When more and more terminal customers and public transport companies in various regions select vehicle configuration, the vehicle bridge with the abrasion alarm indicator is adopted, the abrasion alarm device gives an alarm for the thickness of the brake pad, the thickness of the brake pad is guaranteed to meet the use requirement all the time, and therefore the operation safety of the brake system is guaranteed, and the cost of subsequent maintenance is reduced.

The brake pad wear-out warning device has no wear-out warning function in the prior art, easily leads to the brake pad to be worn out, damages the brake drum, and only depends on periodical disassembly and assembly maintenance inspection for preventing the brake pad from being worn to the limit, but can increase the maintenance cost.

Therefore, there is a need for an improved structure to solve the above problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an external wear indicating device for drum-type axle can demonstrate in real time the wearing and tearing thickness of brake block in order to decide whether need change.

The utility model discloses a following technical scheme realizes above-mentioned purpose: the utility model provides an external wear indication device for drum-type axle, is including passing the camshaft of brake assembly and installing in the adjusting arm of camshaft, the one end that the adjusting arm was being worn out to the camshaft is equipped with the rand, be equipped with the pointer on the rand, the outside of adjusting arm is equipped with the wear indication chassis, the rand is at wear indication chassis internal rotation, be equipped with a contact on the wear indication chassis, work as the pointer with put through an alarm device during the contact.

Specifically, the wear indication chassis is fixed to the adjusting arm through a bolt, and a kidney-shaped hole is formed in the wear indication chassis and used for penetrating the bolt.

Specifically, the outer end of camshaft is equipped with the open slot, the rand be equipped with one back to the pointer and with open slot complex bayonet socket.

In particular, the alarm device is a wear warning lamp connected to the instrument panel.

Compared with the prior art, the beneficial effects of the utility model reside in that:

the device can prompt a driver when the brake pad should be replaced, so that disassembly confirmation is omitted, the utilization rate of the brake pad is improved, and the cost is reduced.

Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example (b):

as shown in fig. 1 to 4, the utility model discloses an external wear indication device for drum-type axle, including the camshaft 2 that passes brake assembly 1 with install in camshaft 2's adjusting arm 3, camshaft 2 is equipped with rand 5 in the one end of wearing out adjusting arm 3, is equipped with pointer 51 on the rand 5, and adjusting arm 3's the outside is equipped with and wears to indicate chassis 4, and rand 5 rotates in wearing and tearing indicate chassis 4, is equipped with a contact 41 on the wearing and tearing indicate chassis 4, switches on an alarm device 6 when pointer 51 and contact 41 contact. When the brake pad is not worn, the pointer 51 is not contacted with the contact 41; when the brake pad is worn, the clamping ring 5 rotates relative to the wear indication chassis 4, when the rotation angle reaches a critical angle, the pointer 51 and the contact 41 are connected with the alarm device 6, and then a driver is prompted to replace the brake pad, so that the dismounting confirmation is omitted, the utilization rate of the brake pad is improved, and the cost is reduced.

As shown in fig. 2 to 4, the wear indication chassis 4 is fixed to the adjustment arm 3 by bolts 7, and a kidney-shaped hole 42 is formed in the wear indication chassis 4 for passing the bolt 7. Since the threshold position is determined by the relative positions of the pointer 51 and the contact 41, the wear indicator plate 4 needs to determine a reference position when fixed, and the kidney-shaped hole 42 allows the wear indicator plate 4 to be adjusted to the reference position by adjusting the initial position to match the reference position while allowing for machining errors.

As shown in fig. 3 and 4, the outer end of the cam shaft 2 is provided with an opening groove (not labeled), and the collar 5 is provided with a bayonet 52 which faces away from the pointer 51 and is matched with the opening groove. Because the installation angle of the camshaft 2 is fixed, the initial angle of the pointer 51 can be determined through the matching of the open slot and the bayonet 52, and the condition that the abrasion of the brake pad is correctly represented after the pointer rotates by a specific angle is guaranteed.

As shown in fig. 3 and 4, the alarm device 6 is a wear warning lamp attached to the instrument panel. Thus, a driver can determine whether the brake pad needs to be replaced by observing whether the wear warning lamp is lighted in the cab.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
