[CN 201780006557.8] Axle guide assembly with longitudinal hydro-mechanical converter and related transmission device Title: Axle guide assembly with longitudinal hydro-mechanical converter and related transmission device Application number: CN 201780006557.8 Applicant: Bombardier Transportation Co., Ltd.; Carl Freudenberg Company Application date: 2017-2-6 Patent type: Invention application This invention relates to a wheel axle guide assembly (10), including: axle box bracket (20); the axle box (14) longitudinally between the front (16) and rear (18) of the axle box bracket (20), the front longitudinal hydro-mechanical converter (32) between the front (16) of the axle box bracket (20), and the rear longitudinal hydro-mechanical converter (34) between the axle box (14) and the rear (18) of the axle box bracket (20), to allow fore and aft movement of the axle box (14) relative to the axle box carrier (20) parallel to the longitudinal direction (200). Each of the front and rear longitudinal hydro-mechanical converters (32,34) includes a housing (36), a plunger (38), and an elastomeric body (40) fixed to the housing (36) and the plunger (38) to allow relative movement between the plunger (38) and the housing (36) parallel to the longitudinal direction (200), A single variable volume hydraulic chamber (42) is formed between the housing (36), the plunger (38) and the elastomeric body (40). A hydraulic port (54) provides connection of the variable volume hydraulic chamber (42) to an external hydraulic circuit (54,56,64,66,68,70,72,74).
