The invention discloses balanced exchange drive of non-hub motors of a high-energy-saving electric vehicle. The balanced exchange drive adopts four non-hub motors for driving simultaneously, wherein four non-hub motor controllers and one pedal hall accelerator control the four non-hub motors to regulate the speed of the four non-hub motors, so that the four non-hub motors work synchronously. The force received by the four non-hub motors is different at the same time when the electric vehicle turns, and electronic differential and self-adaptive control of two non-hub motors are realized by the four non-hub motor controllers, so that driving is safer. The balanced exchange drive has the advantages that (1) four non-hub motors are adopted as drive, so that the heat dissipation area of each non-hub motor is increased, the effective power of the electric vehicle is improved, tire burst caused by overheat is prevented, the anti-skid ability is improved, and the stability of the electric vehicle and the driving safety are improved; (2) the front or rear two non-hub motors respectively do not work because of some reasons, and the other two non-hub motors work, so that the electric vehicle can travel normally, and the normal driving reliability of the electric vehicle is improved; (3) the non-hub motors are special motors, and the motors, the power systems of which are integrated into hubs, and are named non-hub motors, so that the maintenance and the replacement are facilitated, and the tires are easily replaced; (4) the ABX electronic brake is achieved, mechanical brake is eliminated, and labor and materials are saved.

The invention discloses a self-locking type automobile emergency braking system, which is composed of a spring supporting seat, a fixing lock, a rope collecting roller, a sliding arc plate, a clamping plate, a friction plate and a tripod, and is arranged right above each driving wheel. According to the self-locking type automobile emergency braking system, an emergency braking button, which is arranged in a driving cab, is pressed when emergency braking is needed; the emergency braking button is used for controlling an electromagnetic valve switch to open an air reservoir, so that air pressure enters into a cylinder barrel body, which is fixed at the bottom part of an automobile frame, through an air circuit; a piston rod, which extends out of the cylinder barrel body, drives a lock pulling rod on the fixing lock to act, so that a locked retaining ring at the top part of a shock absorber is released; the front part of the sliding arc plate, which is integrally connected with the shock absorber, slips downwards by means of the own gravity; a combined body, which is formed by the friction plate and the clamping plate, slips in front of the wheel along the sliding arc plate, so that the braking is realized, and traffic accidents are effectively prevented. The self-locking type automobile emergency braking system is suitable for various types of vehicles, and is especially applied to heavy trucks and large vehicles.

A mechanical braking device based on a mechatronic self-locking system disclosed in the present invention includes a tooling seat, a transmission cavity is arranged in the tooling seat, a driving motor is fixedly arranged in the rear inner wall of the transmission cavity, and the transmission There is a brake assembly in the cavity, and a transmission cavity is connected to the left inner wall of the transmission cavity, and a plastic tube transmission and cutting assembly is installed in the transmission cavity, and the driving motor can be controlled by the brake assembly. The transmission of the plastic pipe transmission and cutting assembly, the brake assembly includes a first rotating shaft power connected to the front end of the driving motor, the first rotating shaft is connected with a first gear through a first spline connection assembly, and the first rotating shaft The lower end of a gear is meshed with the first ring teeth. This example aims to design a mechanical brake device that has a buffering effect and can shorten the reaction time gap used in the fixed-length cutting tool for pipelines.
