The invention relates to a dual-motor drive system and its shift torque control method, and a vehicle. The first motor and the second motor are respectively set as a main drive motor and an auxiliary drive motor, and a drive motor and a speed-regulating motor, and the main drive motor is judged Whether the maximum output torque MT provided can meet the required torque of the entire vehicle. If the maximum output torque of the driving motor meets the required torque of the entire vehicle, there is no need to clear the torque of the speed regulating motor, and at the same time, the output torque of the driving motor always meets the required torque of the entire vehicle. , no additional torque control is required; if the maximum output torque of the drive motor does not meet the required torque of the vehicle when shifting and clearing the torque, only the speed regulating motor needs to be cleared at this time, and the drive motor works at the maximum output torque at the same time; therefore, shift gears here stage, this method can effectively reduce the probability of simultaneous adjustment of two motors, reduce the motor adjustment time, thereby reducing the shift time, making the vehicle dynamics smoother, and further improving driving comfort.

The invention relates to an automatic head generating device for a coiling machine. The automatic head generating device comprises a motor, a cam, a fan-shaped gear, a top rod, a head generating support frame, a head generating leaf spring, a head generating mandrel and a head generating pipe, wherein the cam is connected with the center of the fan-shaped gear through a mechanical mechanism, the fan-shaped gear is engaged with the head generating support frame, one side of the fan-shaped gear is connected with the top rod through a reset spring, and the head generating support frame is sequentially connected with the head generating leaf spring, the head generating mandrel and the head generating pipe. The automatic head generating device has the advantages that a novel structure is adopted, each part structure is optimized and combined, the power is smooth, the efficiency is high, and the automatic head generation can be completed.

The invention discloses a roller sliding wire which comprises a conducting wheel, a conducting disc, a brush carrier, an electric brush, constant-pressure compressed springs and an outer electric conductor; the conducting wheel is arranged on a chassis through a bearing, and the conducting wheel is in rolling contact with a guide rail; the conducting disc is arranged on the conducting wheel and is in contact with the electric brush, and the electric brush is arranged in the brush carrier through at least two constant-pressure compressed springs, so that the conducting wheel rolls to drive the conducting disc to generate rolling friction between the conducting disc and the electric brush; a lead wire of the electric brush is fixed to the outer electric conductor, the outer electric conductor is connected with the interior of a travelling hoist through a connecting wire, and electricity on the guide rail is conducted into the travelling hoist. The built-in electric brush is adopted to conduct the electricity to the conducting wheel and the conducting wheel is in rolling contact with the guide rail accordingly, so that problem that a contact area between a siding wire on the travelling hoist and a sliding plate is reduced due to sliding wire oxidization, sliding wire deformation and unevenness of the surface of the sliding wire, and when heavy current passes through the sliding wire, the temperature rises sharply to allow the sliding plate to generate electric arcs, the sliding plate is subjected to thermal deformation or even is broken, which result in power failure and production stop is solved, and problems that the replacement cycle is short and high-altitude live-wire work maintenance is difficult are solved.

The invention belongs to the field of a coating and specifically relates to a rare earth composite coating for energy saving and emission reduction of a vehicle and a use method thereof. The rare earth composite coating for energy saving and emission reduction of the vehicle is prepared from the following raw materials: 30-40% of alkyd resin, 8-18% of calcium carbonate, 9-19% of barium sulfate, 1-2% of samarium, 1-2% of neodymium, 0.1-0.5% of lutecium, 0.3-0.8% of erbium, 1.5-5% of a dryer, 1.5-5% of a dispersing agent, 2.5-5% of an anti-settling agent, 9-17.5% of aromatic solvent oil, 9-21% of alkane solvent oil, 5-10.5% of methylbenzene, 3.5-8.5% of a wetting agent and 1-5% of a fire retardant. According to the use method for the rare earth composite coating, the rare earth composite coating is coated on the outer surface of an oil-way oil nozzle of the vehicle and / or in an engine intake tube. The rare earth composite coating provided by the invention has the advantages that 1) the emission of waste gas is reduced, and 70%-90% of waste gas emission is reduced; 2) the burning efficiency of the fuel oil is increased, and 10%-20% of fuel oil volume is saved; 3) the power is enhanced, and the power is increased by above 20%; 4) the noise of the engine is reduced; 5) the coating is simple, and the vehicle body structure is not damaged or changed; and 6) the generation of haze can be effectively relieved.
