Problems solved by technology

In addition, due to the technical blockade imposed by relevant international groups on my country's power drive field, my country currently has no production capacity in terms of high-power engines, gearboxes and transfer cases, and can only rely on imported complete machines or spare parts. to assemble
Its price is not only very expensive, but also consumes a lot of foreign exchange in our country, and also seriously restricts the development of high-speed and heavy vehicles in our country.

Embodiment 1

[0017] A 130KW (175 horsepower) engine and a matching gearbox are refitted on the original 260KW (350 horsepower) traction main vehicle 1, and a 130KW generator set 3 is installed at the rear of the cab. A drive motor 6 of 130KW is installed on the rear axle 5 of 7, and is electrically connected with generator set 3. The result is a hybrid-powered semi-truck that still packs 350 horsepower. The centralized driving of the semi-trailer vehicle to tow the main vehicle is an evenly distributed driving of the whole vehicle, which improves the driving characteristics and improves the driving efficiency. And because the domestic 130KW engine can be used, compared with the original 350-horsepower semi-trailer truck that can only be imported with a 260KW engine and gearbox, its production cost can be reduced by more than 100,000 yuan, and the economy of the vehicle operation can be reduced. There is a substantial increase.

[0018] In addition, more than two on-board generator sets c...

Embodiment 2

[0020] On the semi-trailer trucks with front and rear drives that retain the existing mechanical power drive system, one is to install an electric drive system on the semi-trailer 7, and the other is to change the front axle 2 on the traction main vehicle 1 to an electric drive. Drive, or retain the transfer case, on the basis of mechanical transmission, install the auxiliary drive motor for the front axle 2, and install the auxiliary motor on the transmission shaft or drive axle 4 of the traction main vehicle 1. In this way, the semi-trailer vehicle becomes an all-wheel drive in a complete sense, and then the driving state of each axle or each wheel is regulated by using the existing technical means, which can greatly improve the passing performance and running performance of the vehicle, and save fuel. The effect is remarkable.

Embodiment 3

[0022] Keep the main part of the above-mentioned hybrid drive semi-trailer truck unchanged, but change the power drive device on the traction main vehicle 1 to a drive motor installed on the drive axle 4, and the drive motor is electrically connected to the on-board generator set 3 . In this way, the vehicle is driven entirely by electric motors, thereby eliminating the gearbox and transfer case. The electric drive system can drive individual axles or wheels of the vehicle, and can also drive all axles or wheels, so that the working efficiency of the drive system is improved. In this vehicle, since there are two processes of power generation and electric drive, it also belongs to the working mode of hybrid power.

Abstract

The mixed power driven semi-towed truck is developed for eliminating the limitation of great power driver to heavy truck. It consists of towing truck and trailer, the towing truck is provided with driver and vehicular power generator set and the trailer is provided with driving motor connected to the vehicular power generator set. The semi-towed truck is dispersed driven, rather than concentrated driven, and thus has improved driving performance, raised driving efficiency, improved bearing capacity, towing capacity, climbing ability, accelerating performance, etc. The semi-towed truck has operating power determined based on the practical load and thus obvious fuel oil saving effect.

Description

technical field [0001] The invention relates to a transport truck, in particular to a semi-trailer truck driven by hybrid power. Background technique [0002] A semi-trailer truck is composed of a main vehicle and a semi-trailer towed behind it. A power drive device is installed on the traction main vehicle, and the power drive device generally transmits power from an internal combustion engine to a drive axle through a gearbox and a drive shaft to drive the vehicle to run. Because it is very difficult to work in parallel with mechanical engines, and it is also difficult to arrange two sets of engine and transmission systems on the truck, the existing semi-trailer trucks have no power system distribution on the rear axle of the semi-trailer, and The drive axle on the traction main vehicle is completely driven to run the whole vehicle. Its working method is: the engine transmits power to the gearbox (if there is a front axle drive, a transfer case is also installed), and th...
