Problems solved by technology

[0005] The above-mentioned known technical solutions under the first technical idea have the safety function of run-flat tires, and can ensure driving safety in real time when the tires fail. The disadvantage is that special and expensive tires are used, and fuel consumption increases due to increased tire weight.
The above-mentioned known technical solutions under the second technical idea have their own advantages, but it is inconvenient to install and disassemble

no. 1 approach

[0141] According to the design idea of ​​the present invention, which is not limited to the first embodiment of the present invention, the locking mechanism includes at least one elastic stopper, and the elastic stopper is used in cooperation with the movable coupling mechanism so that all The primary tire side engaging member remains in the locked position.

[0142] As described below, the locking mechanism can have multiple implementations: elastic stop mode, cam lock mode, ratchet pawl mode, gear meshing mode, connecting rod locking mode and other known locking and locking methods that can be used in the present invention. / or locking method.

[0143] Optionally, the elastic stopper includes a pneumatic piston or a hydraulic piston.

[0144] Preferably, according to the design idea of ​​the present invention, not limited to the first embodiment of the present invention, the elastic stopper is a one-way locking member, and the one-way locking member includes a lock block 22...

Embodiment approach

[0152] Preferably, according to the design concept of the present invention, which is not limited to the first embodiment of the present invention, the one-way locking member includes a compression spring 253, and the compression spring applies a force to the lock block 22. The locking position of the locking block 22 is ensured by this force to ensure that the locking block 22 is always in contact with the first friction contact surface 17c and the second friction contact surface 105 .

[0153] Advantageously, without being limited to the first embodiment, the one-way locking member can move between a working position and a non-working position, and in the working position, the first frictional contact surface 17c can only move in the first direction F 1 One-way movement, in the non-working position, the first frictional contact surface 17c can move in the first direction F 1 and the second direction F2 Move freely in both directions.

[0183] According to the first embodiment of the present invention, the working principle of the installation and disassembly of the quick installation and disassembly system 90 is as follows:

[0184] Steps to install auxiliary tire 1 to main tire 3:

[0185] - Place the unpowered jack 50 in front of the main tire 3 to be installed with auxiliary tires, drive the car on the unpowered jack 50, and lift the main tire 3 off the ground;

[0186] - Put the main tire-side abutment part of the locking device 90 in the disengaged position, the articulation mechanism in the hooked position, and the locking mechanism in the unlocked position. Disengage the pressing rod 20 from the lock hook 21, turn the pressing rod 20 to expose the unlocking head 16 of the inner locking rod; Open the hole 16B, pull up the unlocking head 16 of the inner locking rod, let the return hook 16A used by the unlocking lock plate 29 of the inner locking rod 16 be hooked on the top of the outer locking rod 17, ...

Abstract

The invention relates to a system for quickly assembling and disassembling auxiliary tyre for motor vehicle. The system comprises the auxiliary tyre (1) and a locking device, wherein the auxiliary tyre (1) comprises an auxiliary cover tyre (9) and an auxiliary hub (11); and the auxiliary tyre (1) is arranged on a hub (23) of a main tyre (3) of the motor vehicle in a coaxial manner by virtue of the locking device. The system is characterized in that: the locking device comprises a main tyre side bonding part, an auxiliary tyre side fixing part, a movable connection mechanism and a locking mechanism. The system for quickly assembling and disassembling auxiliary tyre for motor vehicle is provided with a connecting channel (51) by which the main tyre side bonding part can pass through the hub (23) of the main tyre (3) and arrive at the radial surfaces (40c and 41c) of the inner side.

Description

technical field [0001] The invention relates to a quick installation and disassembly system for auxiliary tires for motor vehicles, in particular to a quick installation and disassembly system for small or light vehicles and large, medium or heavy vehicles. Background technique [0002] In the prior art, if a tire breaks down during the driving of the motor vehicle, the vehicle is usually stopped, and a tool is used to remove the faulty tire and install a spare tire. These removal and installation steps are quite cumbersome, laborious and time-consuming. It also requires some technical expertise to complete. [0003] In the prior art, there are two known technical routes to solve the above problems. The first technical idea is to arrange various support structures inside the tire so as to ensure that the motor vehicle can safely travel a certain distance after a tire burst. This is in the patent application US 2010 000 647, US 2009165 917 A1, CN 201 494 261 U, CN 201 472 0...
