china 250cc water cooling engine automatic motorcycle trike

china 250cc water cooling engine automatic motorcycle trike is widely used in rural areas, urban areas. 250cc china motorcycle for cargo transport, passenger transport, mobile fruit vending machines, vending.

If an internal combustion engine is used, its cylinder displacement is greater than 50mL, or regardless of the driving mode, its maximum design speed is greater than 50km/h. Including two wheeled motorcycles, side three wheeled motorcycles and regular three wheeled motorcycles (side three wheeled motorcycles and regular three wheeled motorcycles can be collectively referred to as three wheeled motorcycles)

3 wheel motorized tricycle。

In 2014, in order to reduce costs and improve independent management capabilities, the company invested 30 sets of automated welding robots and invested tens of millions in 3 automotive paint lines. There are 2 frame welding lines and a number of R&D patents have been obtained.

In October 2014, the company increased its investment in the production of parts and components, realized the complete self-manufacture of core parts, and set up frame workshop, carriage workshop, cab workshop, rear axle workshop, and stamping workshop 3 wheel motorized tricycle.

 The Dayang brand became the No. 1 brand in Chongqing tricycle sales in 2015.

Main differences between freight electric 3  wheel  tricycle and electric bicycle

3) Brake switch The brake switch of an ordinary electric bicycle is connected to a brush controller. When braking, the conduction ratio (i.e. duty cycle) of the drive pulse of the last stage power switch tube VMOS is reduced to zero; The freight three wheel brake switch is connected with the pull in coil of the contactor in series. When braking, the pull in coil of the contactor is cut off for power supply, and the contactor (normally open contact) cuts off the power supply of the brush controller and even the motor.

Some freight electric  3 wheel tricycles are also equipped with hand brake and foot brake.

(4) Lighting and signaling devices The lighting headlamp, horn, turn signal, brake tail lamp and other auxiliary appliances installed on the freight electric  3 wheel tricycle are all common motorcycle military accessories, and the working voltage is generally 12V. Therefore, the auxiliary circuit needs 12V for power supply. If DC ～ DC circuit is used to reduce 60V to 12V, the cost and failure rate will be high. At the same time, the life and reliability of the lighting headlamp, turn signal lamp and brake tail lamp for ordinary motorcycles are also much higher than those of the 36V bulb for electric bicycles.

1.Hydraulic mechanism  makes the discharge more convenient.

2.Mechanical hydraulic mechanism’s reliable and  cargo safer. 

3.Electronic hydraulic mechanism is easy and convenient to manipulate.

4.The nominal pressure rating  cargo of Hydraulic struts is 3 tons, reaching up to a high level.

  5.Hydraulic cargo is made of channel steel，which is a very good material.

  6.Automatic lock is used on hydraulic cargo, don’t have to manually open the cargo when discharge， which is more convenient.

 7.Hydraulic mechanism contributes to check the other elements which are under the cargo.
