Abstract

If the vehicle is braked on the roundabout, the wheel load will be changed greatly, affecting the stability, braking efficiency, and durability of the vehicle and the road. This paper presents research results on the effect of braking force on wheel load and braking efficiency when a tractor semi-trailer is braked on a roundabout with a random road surface according to ISO 8608:2016. The results showed that, the maximum front wheel load is (1.43÷2.11)Fz1st and the maximum middle wheel load is (0.88÷1.07)Fz3st and the maximum rear wheel load (0.70÷0.95)Fz6st; The left middle tyres slip completely when the vehicle is braked at FB=(70, 80, 90)%FBmax; The rear left tyres slip completely when the vehicle is braked at FB=(50, 60, 70, 80, 90)%FBmax; The rear right tyres slip completely when the vehicle is braked at FB=(80, 90)%FBmax.
