Vehicles with timely four-wheel drive system in the world can be divided into two categories:
1. HALDEX Sweden provides timely four-wheel drive technologies for European cars, such as Volkswagen Tiguan, Golf R20, Audi TT and Land Rover Freelander 2.
2. Japanese cars with timely four-wheel drive technology provided by Japan JECKT Company, such as RAV4 and Highlander.
So, what are the advantages and disadvantages of timely four-wheel drive? Let's see:
1. Advantages of timely four-wheel drive:
The structure of timely four-wheel drive is relatively simple, which can effectively reduce the manufacturing cost and is also conducive to the lightweight design of automobiles.
However, due to the particularity of timely four-wheel drive structure, it is more suitable for front-wheel drive models.
Compared with the rear-drive platform, the front-drive platform is conducive to expanding the spare space in the car, with faster transmission efficiency and less noise when working.
2. Disadvantages of timely four-wheel drive:
Due to the structural limitation, it is difficult for four-wheel drive to transmit more than 50% of the power to the rear axle at a suitable time.
At the right time, the front and rear axles of four-wheel drive vehicles mostly adopt open differential, and the passing capacity of some complex sections is limited, and the off-road strength is relatively low.
