Power is the key point of selecting and purchasing the mixing truck. If the power is well matched, the performance of the vehicle can be maximized to achieve twice the result with half the effort. Therefore, the following items should be paid special attention to when purchasing the fully automatic concrete mixer truck:
1. Selection of engine horsepower
For engines of the same brand, the higher the horsepower, the better the acceleration performance, the better the climbing performance, the higher the high speed under heavy load, and the less the shift times during operation. Therefore, if you want your mixer to accelerate fast, have good climbing performance, speed high, and reduce the number of shifts, it is better to choose a relatively high horsepower engine on the appropriate basis.
2. Transmission selection
Generally speaking, the more gears, the better the climbing performance in the first gear. The more gears, the smaller the change of engine speed in the shift, and the more economical and fuel efficient the use of the whole vehicle; Transmission torque. The rated input torque of the transmission cannot be less than the large torque of the engine. For example, the large torque of WP10.336E40 engine is 1500Nm, which can match the 10JSD160 transmission, but cannot match the 10JSD140 transmission. Gearbox shall be equipped with synchronizer. Gearbox with synchronizer shall be automatically sucked in when shifting, with good shifting smoothness and small shifting impact.
3. Powertrain selection
Advantages of high-power engine+direct gear+small gear ratio: the reduction of high-power gear shift ensures that the engine works in the economic speed zone and has strong climbing power; The direct shift transmission+small ratio rear axle can achieve the same small transmission ratio as the overdrive transmission+large ratio rear axle, and the two configurations have the same economic speed.
Generally, the mixer truck with high-grade driving is often used. It is recommended to use the direct gear+small speed ratio configuration; Frequently use the mixing truck with sub-high driving speed, and use the over-speed gear+large speed ratio configuration.
